Alot of what you say makes sense but the EU can't be blamed for the stupjtidy of the carry on in Westminster
The US have much the same promlems in relation to housing Labour etc and many more countries also.
I think what you say is correct- the problems of the UK are not down to the the EU, but over the last 40 years, they have taken over so much of the regulation and governance of the country, that all we have in Westminster are a bunch of rubber stamping muppets, who are incapable of running the country without looking for some sort of EU directive.
Get out of the EU and make our politicians hang by their own tail, instead of them always looking for the EU to blame.
