at least the american artists are not good for biz logics. cannot really do simple math, but then they are not really supposed to: they need to utrn out great art works, and those who trained with biz ought to help him/her maximize the financial return for him.
but, i met several chinese artists who were born with more talents in money than in art: it was really unfortunate the biz world did not have them: without training these guys by instincts know how to make big dollars! the american trained MBAs are no match for these guys.
