open, but well regulated, markets are the only practical way for an economy and society to sustainably provide for itself.
communism is a very nice theory, i would absolutely love to live in a smoothly running communistic society like the one described in the book "Utopia" (if you havent read the book i encourage you to do so, the society truly is a Utopia if one could ever exist)
but in reality we must use the profit incentive and the market system to distribute goods and services.
this isnt to advocate for laizzes faire or trickle down economics either.. on the contrary taxations and regulation are both quite necessary to sustain the economy, to prevent cyclical recessions/depressions, to ensure the freedom of individuals to operate unoppressed and in a system where oppurtunity for upwards mobilization is possible... etc..
