Gonna aim for one short sentence each.
Socialism is a mode of production superseding capitalism that lacks commodity production, wage labour, etc. and this has never been reached yet.
Freeing the market doesn't replace unfreedom with freedom but only replaces explicit control by government with implicit control by market forces, which is less apparent and thus even more powerful.
One of the fundamental characteristics of a communist society is lack of commodity exchange and therefore lack of currency, whereas all of the aforementioned states have their own currency.
Money doesn't operate under socialism at all, so the two systems are incommensurable in terms of the amount of money one makes.
Money doesn't operate under socialism at all, so that's a question for a social democrat like, for example, Thomas Piketty.
Production under socialism can help people even more because then all production is aimed directly at serving human need (production for use) rather than at extracting profit (production for exchange) like in capitalism.
The goal of communism is a free association of producers rather than a big controlling government, so this charge should be directed at someone else.
A lot of which are detrimental to our lives and could be put to a much better use under a system directed at improving people's lives rather than addicting them to crappy mobile games and extracting profit.
Most of the ways we currently measure success only make sense under capitalism and are unrelated to actual human flourishing which would, under socialism, improve even for those successful by capitalist standards.
The way labour is organized under capitalism makes most people miserable, so if they value money so much this is most likely a rationalization that helps them cope with the grim reality of alienation by trying to fill that enormous hole in their being with commodities.
Why do you tolerate a system under which people are so poor that they can't even support their babies?
