Instead they have had their standard of living, in real terms, degraded and the war has been waged on them by the rich elites. Soon they will all be serfs to the corporatist feudal lords.
So why are so many countries desperate to join the EU? Is it perhaps because they have seen the track record of the EU in developing the economies and standard of living of people in rather under-developed and poor countries to a state where they are broadly equivalent to the more established european economies. Being part of the EU makes countries richer and their people, from top to bottom, richer.
I think if you want countries that are really in thrall to corpora list feudal lords you should look across the Atlantic and perhaps to the kind of vision that Farage, IDS and Redwood would like in a post-Brexit UK, but which can't happen currently due to the tempering influence of the EU.
Don't forget that quote from Rupert Murdoch when asked by Anthony Hilton why he was so opposed to the European Union.:
'That’s easy, when I go into Downing Street they do what I say; when I go to Brussels they take no notice.'
