The government has lost the economic argument around immigration

It now straddles two contradictory claims.

Gus O'Donnell, the former head of the civil service, has written in an article in the Times that the government is "shooting itself in the foot" with its desire to lower immigration.

He writes (£):

A big barrier to growth is an immigration policy that deprives the UK of skilled workers in certain disciplines. Lord Heseltine, while at pains to avoid criticising the Government, clearly sympathises with the difficulties that businesses face in recruiting these workers.

O'Donnell's criticism piles on the pressure the government is facing to justify its immigration policy in economic, as well as just populist, terms. As he mentioned, Heseltine's review, No stone unturned (pdf), also tactfully steers a course rather different to that currently being pursued by the Home Office.

Heseltine writes:

It goes almost without saying that the ideal solution is a well-managed immigration system that is open and welcoming to those who can address our skills gaps and add value to the economy, yet is unattractive to those who do not have and would not get permission to be here. This is easier said than done at a time of tough manpower constraints in the public sector.

While it "almost goes without saying", that is not actually the government's own strategy. The Conservatives are locked into a damaging attempt to bring net migration in under an arbitrary cap; and worse, they have no power to affect the biggest single contributor to that number, which is intra-EU migration.

As a result, the party is forced to attack the small sliver of migration they can have an effect on. But unskilled, non-EU migration had already been extremely constrained by the previous government, so to limit immigration any further, skilled migration came under fire. Even with new strict measures on visas, the government is losing the fight miserably. Its target is net migration of 100,000 people; the latest figures show that number is 216,000.

Politically the government is failing. It has set itself a challenge which it will not – cannot – meet. That alone would be a reason for abandoning the aim now, nobly accepting defeat, even if that figure weren't one which no sane government ought to try to achieve.

Last week's Economist leader laid out the problem the economy faces as a result of this policy in stark terms:

The country has, in effect, installed a “keep out” sign over the white cliffs of Dover. Even as Mr Cameron defends the City of London as a global financial centre, and takes planeloads of business folk on foreign trips, his government ratchets up measures that would turn an entrepôt into a fortress. In the past two years the Tories have made it much harder for students and foreign workers and family members to enter and settle in the country. Britain is not only losing the war for global talent, it is scarcely competing. More people now leave to take up job offers in other countries than come the other way.

In fact, even the nascent pro-immigration voices on the right don't take the argument far enough. While many of them are content to make the argument that immigration represents a favourable trade-off between unemployment and growth, few take the extra step of point out that immigration can help with both employment and growth. This argument involves tackling head-on the pervasive "lump of labour" fallacy – the idea that there are a fixed number of jobs, and if a foreigner gets one, then a Briton can't.

Forbes blogger Adam Ozimek writes about Silicon Valley, where a similar argument is taking place after a technology journalist, Robert X Cringley, has criticised skilled-migration visas:

Imagine the worst case scenario in Cringely’s mind occurs, and a foreign worker takes a job at a 30% discount, and a native worker who could have had the job has to settle for a lower paying job. To understand the impact on U.S. workers you have to look beyond this worker who has had his job “stolen”, and must look at what economists call the general equilibrium effect. Here are other things that happen: the H1-B worker buys or rents a home, and a landlord of home seller benefits, overall, new houses will be built, meaning construction workers benefit. The H1-B worker shops at a grocery store, which employs workers, and sells goods made by farmers who also employ workers. See how this goes?

The economic case for limiting migration is thoroughly lost. At best, the government is now facing the risk that this argument filters into the popular perception; at worst, it is in the position of encouraging a popular attitude which is simply incorrect.

The Telegraph’s bizarre list of 100 reasons to be happy about Brexit

“Old-fashioned light bulbs”, “crooked cucumbers”, and “new vocabulary”.

As the economy teeters on the verge of oblivion, and the Prime Minister grapples with steering the UK around a black hole of political turmoil, the Telegraph is making the best of a bad situation.

The paper has posted a video labelled “100 reasons to embrace Brexit”. Obviously the precise number is “zero”, but that didn’t stop it filling the blanks with some rather bizarre reasons, floating before the viewer to an inevitable Jerusalem soundtrack:

Cheap tennis balls

At last. Tennis balls are no longer reserved for the gilded eurocrat elite.

Keep paper licences

I can’t trust it unless I can get it wet so it disintegrates, or I can throw it in the bin by mistake, or lose it when I’m clearing out my filing cabinet. It’s only authentic that way.

New hangover cures

What?

Stronger vacuums

An end to the miserable years of desperately trying to hoover up dust by inhaling close to the carpet.

Old-fashioned light bulbs

I like my electricals filled with mercury and coated in lead paint, ideally.

No more EU elections

Because the democratic aspect of the European Union was something we never obsessed over in the run-up to the referendum.

End working time directive

At last, I don’t even have to go to the trouble of opting out of over-working! I will automatically be exploited!

Drop green targets

Most people don’t have time to worry about the future of our planet. Some don’t even know where their next tennis ball will come from.

No more wind farms

Renewable energy sources, infrastructure and investment – what a bore.

Blue passports

I like my personal identification how I like my rinse.

UK passport lane

Oh good, an unadulterated queue of British tourists. Just mind the vomit, beer spillage and flakes of sunburnt skin while you wait.

No fridge red tape

Free the fridge!

Pounds and ounces

Units of measurement are definitely top of voters’ priorities. Way above the economy, health service, and even a smidgen higher than equality of tennis ball access.

Straight bananas

Wait, what kind of bananas do Brexiteers want? Didn’t they want to protect bendy ones? Either way, this is as persistent a myth as the slapstick banana skin trope.

Crooked cucumbers

I don’t understand.

Small kiwi fruits

Fair enough. They were getting a bit above their station, weren’t they.

No EU flags in UK

They are a disgusting colour and design. An eyesore everywhere you look…in the uh zero places that fly them here.

Kent champagne

To celebrate Ukip cleaning up the east coast, right?

No olive oil bans

Finally, we can put our reliable, Mediterranean weather and multiple olive groves to proper use.

No clinical trials red tape

What is there to regulate?

No Turkey EU worries

True, we don’t have to worry. Because there is NO WAY AND NEVER WAS.

No kettle restrictions

Free the kettle! All kitchen appliances’ lives matter!

Less EU X-factor

What is this?

Ditto with BGT

I really don’t get this.

New vocabulary

Mainly racist slurs, right?

Keep our UN seat

Until that in/out UN referendum, of course.

No EU human rights laws

Yeah, got a bit fed up with my human rights tbh.

Herbal remedy boost

At last, a chance to be treated with medicine that doesn’t work.

Others will follow [picture of dominos]

Hooray! The economic collapse of countries surrounding us upon whose trade and labour we rely, one by one!

Better English team

Ah, because we can replace them with more qualified players under an Australian-style points-based system, you mean?

High-powered hairdryers

An end to the miserable years of desperately trying to dry my hair by yawning on it.

She would’ve wanted it [picture of Margaret Thatcher]

Well, I’m convinced.

I'm a mole, innit.
