Wealth inequality is a red herring and a silly metric to consider in this conversation (and probably any conversation). Everything else the same, would you rather live in a world where the average person makes $100k/year and the richest person is worth $1T, or a world where you make $1k/year and the richest person $1M? Because if you're focusing on minimizing "wealth inequality", I guess you'd choose the latter, which is clearly the wrong choice.
Not sure I understand what you mean about "choosing" to live in the 21st century. Yes, you didn't choose the century, but lucky you, you got born into the one with more baseline access to material wealth for the average person than any other century before it. Sucks to be us, eh?
Your final point is objectively untrue. I don't know what your friends do but there are many (not highly-skilled) jobs that pay enough to easily afford all the listed things.
