Yes, as long as they have enough to survive, people generally have some free time. I know someone who's living paycheck to paycheck and they make music as a hobby. Obviously, if you have to work 16 hours a day to survive they wouldn't do it – or at least they wouldn't have the capacity to share it.

No, probably not. Isn't it a shame we live in a world where we have the technology to automate all meaningful production, but people still need to justify their existence through often meaningless labor?

That said, I know artists that make the bare minimum to survive, on purpose, so they have more time to focus on art.
