Chomsky's idea of equal income under anarchism

Noam Chomsky thought that an anarchist society would be essentially egalitarian, not only in rights, but in income. He thought possible for a baker and a neurosurgeon have the same amount of income, since (in a non-capitalist society) both work on their own command, and their work is gratifying in itself.

I was wondering if this idea specifically is mainstream/almost ubiquitous among anarchists. And also your thoughts on the idea.
