We have more debt, less education, worse health, less freedom and lower social mobility than before the socialists got control of the chequebook. By which criteria would this not be counted as a failure?
While I don't doubt your numbers I fail to see what socialism has to do with it. It seems that it has more to do with a lack of financial responsibility, which is common everywhere. Greece, Italy and Ireland were controlled by the right and still managed to screw up royally, while socialist Norway have a very good track record of keeping its finances in order. I do believe that Norway is the only European country that has financed it's pensions, despite several attempts to use the oil funds to pay for other things.
Meanwhile I think it's the socialists who are spearheading Greek return to fiscal responsibility.
Now I don't think that it has anything to do with being socialist, conservative or libertarian, or what have you. I think that certain people are responsible and some are not.
Clinton was responsible and even tried to make a law that all tax cuts had to be financed before they could be implemented. Bush, not so much. Obama, well, not sure really.
