[MD] Are we the people stupid?

[Arlo J. Bensinger]

[Mike to Platt]
A measure of suspicion of human nature also underpins capitalism, which is
considered valuable because it gives 'layabouts' an incentive to work, when
they could otherwise leech from the welfare state.

[Platt]
Capitalism is considered valuable because "A free market is a Dynamic 
institution." (Lila, 17)

[Arlo]
Which does not answer the charge at all, does it? (Big surprise)

Capitalism supposes that people only labor for personal profit, or self-gain.

Communism supposes that people would labor to better humanity with no concern
for their own profit.

Which one is "correct" aside, which one holds a lesser view of human nature?
