I am not interested in descending into an idealogical argument here, but most (serious) anti-capitalist criticisms will acknowledge that capitalism has brought the hitherto highest quality of life, just that it is self-constrained by the necessity to produce for profit.

Socialism is then understood as the overcoming of this constraint, but as always if you ask n socialists/communists you get m answers, where m > n.

It is messy and tiresome to discuss, especially when everyone insists that their personal understandings of what terms mean are the only real ones. More so when you've heard every position a dozen times already...
