well it's an extremist viewpoint isn't it
communism doesn't work because there's no incentive, and on the other side of that, capitalism doesn't work because it completely neglects the needs of the poor.
personally i'd err on the side of lightly implemented communism (i believe the term for it is just socialism) with a capitalist slant; free enterprise for the majority of commercial industries, with a very robust public services sector, extremely high rates of taxation (taxes are always way too low IMO), and an increasing scale of tax up to a ~~ 80-90% top rate for people who have £1,000,000 +
that way you'd still have a decent amount of free enterprise, but not to the extremes of increasing wealth gaps and mass neglect of the public services we have in all of the western cultures today
Couldn't have put it better myself mate, +1. As to the OP, its sad to hear you are leaving mate due to these reasons. While I appreciate what you say, this is the internet largely dominated by Western so called free speech, so developing a hard skin is truly vital in order to carry on ignoring a the bullshit that is thrown at you (which im guessing you have been doing since entering the interwebz). Anyway, good luck!
P.S. its nice to see some political discussion going on, and with some many of the community with good heads on their shoulders who seem to be more left/ socialist leanings
P.s.s Hasta la victoria siempre!
