Your idea has been tried, literally tens of thousands of times. The pie got smaller.

Just in the US alone, 20,000 communes have been formed (they're not illegal). They all failed. Even the diehard communists can't stand living in a commune and sharing equally.

I never proposed any system to obtain equality, merely pointed out that equality as a quality in itself is worth striving for.

A lot of people would argue that the American-style capitalism way is the way to obtain equality and I would not oppose that
