Communism

Declared by who?

Implicitly, by everyone that does not herald the successes of those self professed socialist economies. Explicitly, by too many individuals in too many circumstances to usefully list.

I would much rather be living in a tier 1 city in China right now personally. Or in Cuba if the US ever stopped strangling it.

I mean this sincerely; please move. If you are correct, you will benefit the world overall and yourself.

I agree, David Ricardo was incorrect, and Marx’s refutation in his theory of value explains the creation of value much better. (Imagine reading Marx and not Wikipedia on Marx)

I have only read "Das Kapital", and only by translation. Marx directly asserts the equivalency between the value of a good, and the amount of labor-time that it takes to produce that good on average (accounting for the labor-time that it took to produce tools and raw materials necessary to that process). That is the labor theory of value in a nutshell.

artificial scarcity is a product of commodity fetishism (necessary for capitalism to function)

If you believe that the scarcity we face is largely artificial, then either move to a country further on its way to communism, or start a company that will pay workers a more equal share of the value they produce.
