If you have some free time and aren't easily depressed, go ahead and look up the backgrounds of your favorite, recently ascendant artists. Many, if not most of them come from privileged backgrounds, have wealthy spouses, trust funds, or familial industry connections.
And while I personally don't think that such advantages necessarily diminish the importance of their art, just think of how much more potentially moving and profound work we'll never see just because the people who should be making it never got chance to develop, since they've been too busy just trying to keep a roof over their heads.
