I know the Thatcher quote. I know most of the quotes you keep putting up as evidence of what I'm not sure.
Thatcher was despised when she left office, thrown out by her own party. She never once won close to a majority of the popular vote in the UK.
You made two assertions you cannot back up. One, that Obama is recycling a 150 year old failed philosophy (Marxism I presume since the manifesto was published in 1848). And that all socialist systems degenerate into Stalinism. You can't answer either because Obama is not a Marxist and not even a Socialist and you certainly cannot point to any Social Democratic state becoming Stalinist.
As for Greece, yes it's a basket case. Bad management can happen in any type of economy. Ireland has a much more free market economy and they are a basket case as well. Furthermore, no one in the US is advocating age 50 as the retirement age. In any case, you might have noticed I do not condemn Capitalism entirely as you do Socialism. I think elements of both are necessary for a functioning society. Its that balancing act where the debate exists. What I object to, and think is incredibly silly is the simplification of these issues into pithy quotes and ridiculous assertions that label Liberals in this country as Marxists and Stalinists.
