OK, let's turn to a discussion on socialism.
Disclaimer: The following is just a personal opinion along with a few facts to support it.
Socialism does not include controling the market. That is usualy leftist authoritarianism, although rightist auth. have done so in the past as well.
A radical form of socialism is communism, and it have been empiricaly shown, that communist along with a severely controled market simply collapses on economical grounds. There is no way such a system can sustain it self because it is way too rigid to adapt to changing conditions, unless it is practised on a very small scale, like the
kibbutzim in Israel.
Milder forms of socialism are charachterised by high taxes and generous public service. To my knowledge, Sweden is one of the farthest left-oriented countries (economically), with a combined tax rate of about 70% or more. Public transport, education, healthcare and much more is available for free to all citizens. In the eighties/early nineties, the United States would be considered the opposit of this, when Ronald Reagan minimised taxes, from about 67% to something around 35%. I have no clue about the state now. Americans pay for most healthcare, transportation and many educational facilities.
hehe... enough from me...for now!
