It's clear that a certain free-market vision sees the EU as a cost to business, especially small business.

There has long been a split in in Capitalist political thinking about the relative merits small business verse large corporates... and the more anti-state they are, the more likely they are to believe that the large corporates are buying their way to their neo-monopoloy positions. They have the same thinking about the EU as a bosses-club that some of the left has.

As part of this thinking the free-marketer believe the EU regulatory framework is cost on dynamism because new firms - the fire of Schumpeter's Gale - tend to find paying for their externalities a barrier to growth and the larger encumbents go unchallenged.

In addition, their sovereignty issues are all about tax rates.

I'm not a lexiter. I think it's a mistake to think that in a Britain unfettered by the EU that the struggle between the boses and workers will be fairer and easier to win. IMHO this is blinkered reading of the balance of forces in which socialists ignore their own weaknesses and delusionally blame it on a leviathan.
