Communist countries dictated by political fiat where labor resources were allocated, what industries would be engaged in, and how the capitalized wealth of the country would be reinvested.

They didn't just go around giving everyone an income that kept them from living in a gutter.

That's a facile and inapt comparison that does not aid this discussion.

I thought communism (theoretically) was more similar to a universal shared maximum income.

Socialism in Europe manifested itself in the form of huge public sectors, where virtually everybody was guaranteed a job doing something; the complete opposite of this proposal.

Really? You're gonna compare this to those pathetic excuses for communism?

Which ones?

Twen cen communists failed by trying to pick winners. It proved impossible for central planners to, for example, determine exactly how many meters of type 2 copper pipe to manufacture. They would end up in absurd traps like not being able to expand copper pipe production because of a shortage of copper wire.

That is nothing like giving people €1000 and letting them decide how much if any copper products to buy.
