Come on over Castro, You have won!

I been trying to think and this is hard for my old brain. I have been thinking about the government buying into the banks that are in trouble In short this means the government would have stock in some banks and could lead to nationalizing the banks or partly nationalizing these banks.
I did what I usual do when I want an answer , I google the question.
I could not find a defiant answer to this action , good or bad.
I did read that Obama thought this was a wise course of action but couldn't read much as to what this would mean. If Obama is elected then we could see more of this because he thinks it a good idea.
Most who were for this stated that if this course wasn't followed we were headed for a deep depression.
Then I dug deeper and some people said a national bank was Socialism. Socialism was born out of Karl Marx theory. Am I correct isn't this communism?
We thought democracy had over powered Communism right?
Will Russia have the last laugh and see our capitalism turn communism? I searched more and found..
Socialism is not a discrete philosophy of fixed doctrine and program; its branches advocate a degree of social interventionism and economic rationalization, sometimes opposing each other. Another dividing feature of the socialist movement is the split on how a socialist economy should be established between the reformists and the revolutionaries. Some socialists advocate complete nationalization of the means of production, distribution, and exchange; while others advocate state control of capital within the framework of a market economy. Social democrats propose selective nationalization of key national industries in mixed economies combined with tax-funded welfare programs;
My take on this is if banks were nationalized this would be socialism but I still don't know if this is good or bad. so I Read more...

The Frankfurt Declaration of the re-founded Socialist International stated:

“ 1. From the nineteenth century onwards, Capitalism has developed immense productive forces. It has done so at the cost of excluding the great majority of citizens from influence over production. It put the rights of ownership before the rights of Man. It created a new class of wage-earners without property or social rights. It sharpened the struggle between the classes.
Although the world contains resources, which could be made to provide a decent life for everyone, Capitalism has been incapable of satisfying the elementary needs of the world’s population. It proved unable to function without devastating crises and mass unemployment. It produced social insecurity and glaring contrasts between rich and poor. It resorted to imperialist expansion and colonial exploitation, thus making conflicts, between nations and races, more bitter. In some countries, powerful capitalist groups helped the barbarism of the past to raise its head again in the form of Fascism and Nazism.
I don't know much more than I did before I started this search.I am old and full of days and my life will soon be over so this is a mute issue with me but not for my children and grandchildren.
I did decide that perhaps our country is headed down the road to socialism, I didn't decide if this was some thing that we could avoid or You could avoid because I wont be here.
