Why go main when your money comes direct if you fund your own label? Look at Chamillionaire, the man has some of the dopest rhymes I ever heard freestyle or written, own website, under a label with the rest of his crew and they're sellin cd's at 15 dollars a pop, an people buy them whether it's 10 tracks or 2 cds. Plus add that to funds gained from live shows/appearances, there's no point in him goin major cuz he already turned down Def Jam.

Basically if your makin your money underground your not lookin to go main, I'm pretty sure even 50 (even tho hes nothin special) would have stayed with mixtapes if not for the opportunity to work with Em & Dre. It all depends on the artists situation, if they're satisfied, you won't see them tryna get on MTV or BET, so mainstream and underground would never merge or swap. Besides that's like seein some half-decent local rappey gettin a music award...... nonsense
