Edit: Changed title to be more accurate.
Also here is the summary from Wikipedia on what Post-scarcity means:
Post-scarcity is a theoretical economic situation in which most goods can be produced in great abundance with minimal human labor needed, so that they become available to all very cheaply or even freely. Post-scarcity does not mean that scarcity has been eliminated for all goods and services but that all people can easily have their basic survival needs met along with some significant proportion of their desires for goods and services. Writers on the topic often emphasize that some commodities will remain scarce in a post-scarcity society.
Capitalism incentivizes production so well that the mere charity of individuals provides more for free than all the redistribution the government can manage under a controlled economy.
Capitalism’s primary activity is commerce, with a tiny sliver of charity on the side. That tiny sliver of charity is the biggest pool of resources made available for free under any system.
In what unicorn world are you living in? There are so many subsidies for so many sectors that it isn’t even funny. Capitalism is parasitic at its core and the only reason there is charity from the rich is for the good publicity.
The society is already wealthy, but all the wealth is drained in the hands of a few.
