Most artists don't make enough, though? Isn't that famously well known? Picasso was never rolling in it, burned his paintings to stay warm, and had trouble even eating.
Worse still, you're perpetuating a debunked myth of a starving artist. 99% of the artists you've heard of were able to support themselves with their craft - those that weren't stopped producing and that's why you've never heard of them (a prime example of survivorship bias). Van Gogh is an extreme outlier.
This seems both a) vague and b) based on a sample size of n=1. 85% of all visual artists in the U. S. make less than 25k/year [0]. Also, don't forget that most artists work in companies (again: visual art), like making story boards for anime etc.
