Why is the Capitalist economy so weak, why is that a small country, Greece,can make so much havoc?

Capitalism is a house of cards, built on debt, supported by poor workers and maintained to keep a few living in unimaginable wealth.

It's not the capitalism that cause Greece's mess to multiply.

It's the fact that Europe is on one single currency.

In the past, Greece could have gotten out of their mess simply by creating inflation.

It would have caused the Greek currency to drop with respect to the other European countries' currencies, but would have solved the problem.

Now, with Greece on the Euro, that option isn't available.

Last time I checked Non Capitalist countries like Cuba, North Korea, and Venezuela are NOT economic powerhouses. How do you explain that ?

Too many socialist policies keep them from being able to save money.
