Do artists deserve royalties from unique works with every sale?

Every time a copyrighted book is purchased, the copyright holder receives some royalties for that. The same applies to recordings of music and other intellectual property. However, if an artist sells a painting, no matter the future value of that painting, he receives nothing but the original sale price. Is that fair to the artist? Should he be paid royalties with every sale? Or can he legitimately demand royalties only for the prints of his work?
