Artist or not? yes
How well can you draw? meh... so so..
Artists = richest? hell now way, i am on Gaia but not because of my art (i did consider selling my art one time though.)
How people never want to pay for any other useable skill, other than art? well i dont think their really truly is anouther skill people would pay for, unless its belly dancing or to a world famous footballer or something.
