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.

Simply providing people with the answers is not enough you actually have to make them believe those answers, and there’s always going to be people who are desperate to not accept those answers because doing so would make them the same as everyone else, and of course that’s not possible because they are special. And they are special, just not in the way that they want to be.
