Amorea, you are correct. In fact, for 70-80 years, since the years when socialism and socialist politics were enormously popular in the U.S., the government has been terrified of workers organizing. The cold war only added to the situation and consequently we have had 70-80 years in which, due to heavy propaganda, any open discussion of the pros and cons of capitalism, socialism, and/or communism has been taboo.
If there is any doubt, consider how you feel about your own prospects for raising a positive position on socialism or communism publicly. There is strong hesitancy. That is the virtual taboo to which I refer. And such hesitation is not found in the citizens of European nations because they didn't have the heavy exposure to propaganda that we've had.
Socialism is collective worker ownership and control of industry and businesses. That condition has never existed in any country anywhere at any time as a finished, stable, effective economic form. So no country has been socialist. And Marx's communism is even a more remote idea.
Capitalism took something around 100 years to get established as a national economic model as well. There were failures. There were problems with figuring it out, -how to make it work and make it stable. So any objection that socialism has "always failed" is hypocrisy.
The approach of the USSR and China presented real, known problems. Since their collapse into state capitalism, socialist around the world have studied what went wrong and what to change in our theory and practice. Solutions are now known well enough to propose and put into action. I find this very encouraging and promising.
I could go on for several pages but I know better. Enough for now. Questions? Clarifications?
