Give Britain the boot if it doesn't join up

Throw Britain out of the EU and humiliate the country as much as possible as it's given the boot.
And then: really make this country pay. Begin by closing off all the opportunities to the "bullshitters" (In the Guardian's economics editor's words) that form the mainstay of this country's economy:

[Japanese and Germans have strong economies]
The French have an ultra-competitive manufacturing
base that specialises in food and drink; the
Scandinavians are a dab hand at mobile phones; the
Americans do computers, aircraft and movies; even the
poor, benighted Italians have upmarket designer
clothes. So what is Britain good at? Where does the UK
fit in this world of changing economic geography, in
which nations will increasingly concentrate on the
things they do best? The answer is simple.

We count the money and we do the bullshit.

Britain, on the 10th anniversary of Tony Blair's
arrival in Downing Street, is a place whose default
mode for earning its crust is to employ the gift of
the gab. The Germans may have the engineers, the
Japanese may know how to organise a production line,
but the Brits have the barristers, the journalists,
the management consultants and the men and women who
think that making up jingles and slogans in order to
flog Pot Noodles and similar products is a serious
job. It has the deal-makers in the City who make fat
fees by convincing investors to launch bids for
companies, and the corporate spin doctors who tell
former pals in financial journalism that tycoon X will
make a better fist at running Ripoff plc than tycoon
Y.

It has the publishers and it has the "film
development" companies, some of which have actually
been known to produce a film.

The four iconic jobs in 21st-century Britain,
according to a thinktank called the Work Foundation,
are not scientists, engineers, teachers and nurses but
hairdressers, celebrities, management consultants and managers.

These jobs are very evanescent and depend on social good will.
The Brits can repent at leisure. Or maybe that's what they want. Apart from bits of London, this country is a dump.
Not only is this a consequence of delusions, it's also a cause of them, a liferaft.
