Hardly. The countries that aren't doing well now were economic basketcases 40 years ago.
What 1973 has to do with 2013?
As for now in the EU there are a different economies and different systems by and by. Also introducing common currency with Central Bank was more of the political decision than economical. Not to forget that the world do not end with the EU there are others players in the game.
The problem is that system do not work and will not work. The EU is a good idea as a means of economical coordination between the nations and as a common duty free marked but closed for outsiders.
That could work given right organization. All those bureaucratic overburden and all those political directives should end up in the bin, they are redundant. If that would work in the future the EU could become something more but not very soon.
The problem is that the EU is seen by some as a means to the end and as project for Europe's future.
Ireland for example was crushingly poor in 1973 - it's now one of the wealthiest countries in Europe.
Well Ireland is a different issue here a bit more complex to explain than simple accession to the EU.
The gap is there, but it's closing.
Really - tell it to Greece or Spain, but in the first place tell it to Poland.
German is the strongest economy and is the main benefactor of the EU. All politician and all the EU eurocrats are responsible for the mess in the EU countries - there is no point in blaming local politicians.
I would love to see what happens if Germany leaves the EU.
Oh just cut the crap will you. you know very well that those Germans that are talking about it do not have a say in Germany politics and they are on the fringe of politics.
The general public in Germany will continue to see nothing wrong in the EU unlit they would be hit by crisis or other financial disaster - then they really consider other option. As for now they are just like fatties in the candy shop!
