Britain has suffered from EU membership as a result of the rules aimed at enhancing the farming communities of France and Germany (CAP) at the expense of the rest of the EU - Britain is a net contributor to the EU - it pays more in than it gets out - also the mind-numbing regulations ( I believe several thousand a month) which emanate from the EU are rigorously applied in the UK whereas from what I can see in France etc the authorities take little notice of such things
Britain now has few local family Bakers / Butchers etc etc - not just because of Tesco and the supermarkets but because of EU legislation -
1 example
A couple of years a go a Health Inspector ordered a butcher to stop using his wooden "block" to cut meat on as it was not "banned" by EU dictat (not UK Parliamentary Law but EU directive) - at great cost the block was replaced with new plastic surface - which the butcher knew would be unsuitable but it complied with the law - recently the same inspector visited and ordered the buther to buy "a wooden block" as that was now the approved surface for working on - the inspector was reminded of her earlier visit but could not see how ridiculous this was. Incidentally - all butchers and many other traders are not allowed to have premises in which room corners are not curved (for cleaning) and thousands of bakeries closed after that was applied - bet no French Bakery worried about the rules though......
Legislation such as "The Working Time Directive" requires employers to keep copious records (for years) about who worked when and for how long - what breaks they had etc etc etc
Now another regulation from the EU bans traders accepting cash in amounts greater that 10,000 euros as a money laundering protection - customers who use large amounts of cash have to present their EU Passport and the trader must copy this and report any suspicions to the Police. Accountants must report clients to the Police if they discover trivial errors in company accounts - all rules from Brussels (the EU)
Latest is that any UK employer must see the Passposrt of all new employees and make a copy - if he does not then he faces 7 years in prison.
