Socialism is limited by the fact that the capitalists control the dollars. Too often people in the USA seem to equate socialism with communism, and regard capitalism as some demi-god. Canada tends to follow that thinking as well, but at least has socialized mecicine and to a lesser degree, education.
To be more truthful capitalism is totally greed motivated and can only succeed by some being able to take more than their fair share. What I find confounding is that often those who are first to defend that system are often it's victims.
If we were to equate the economy of the world to a pie, we would find some getting fat eating their own portion plus the share of those who are starving. That is capitalism at it's finest and is not something to be proud of.
I know that I digress but a capitalist goal of today is to control the world's supply of water and if they were to gain that, we would be paying through the nose at more than rock concerts!
