Greed:
I don't believe that fettering greed (ie, desire for money or power) is possible.
Instead, fetter behavior, eg, no stealing, no ruining the environment, no monopolies.
Stealing:
We're going to tolerate some stealing, at the very least from government taxing
us to do desirable things. We should not tolerate stealing which fails us, eg,
taxing us to wage useless wars, to imprison vast segments of the population.
We should enjoy our greed within the useful rules of the game.
Capitalism vs communism vs socialism:
My views are perhaps a smidgeon less black & white than you think.
Capitalism is wonderful. But the political reality is that we need some
regulation of it. An advantage of it is that it enables enuf taxation to
achieve desired social goals, eg, guaranteed income, health care.
Marx:
He'd fit right in on RF....all criticism....terrible proposals....no real world solutions.
He's a loonie gadfly so dangerous that he makes even L Ron Hubbard look good.
(That one was fun.)
