There are many factors that together have put Greece in the situation it is in.
"Socialism" is not one of them.
Only if you only take 'socialism' to mean pure socialism and not what the posters here use the term as (the idea that the government needs to redistribute the wealth to those more 'deserving')
Again, the word 'socialism' is being misused.
Let's call it 'redistributionism' because that might be more accurate.
The reason socialism is so difficult to describe is because there has never been a successful socialist economy.
Bird brained egghead revolutionary despots keep trying and failing and another despot and moron tries it again and fails and another idiot tries it and fails and another douchebag tries it and fails, etc ad nauseam.... All in a slightly different way
But they all have one thing in common -- Redistribution of wealth -- and failure.
Capitalism sucks but it is the only economic system in history that works in the support of a free society.
EVERY other system ever devised inevitably falls into totalitarianism..... Every time
