This is certainly the way it used to be, but nowadays any musician can buy enough equipment to get started in any genre even if they're making very little money. With a few hundred and definitely a couple thousand dollars, anyone with the will to do it can put together a "bedroom studio" that will rival any record label in production quality. There is little to no value in an artist taking $50k in debt (as unlikely as the scenario is to be in the first place) for production. So that only leaves marketing and promotion, which allegedly the labels do, but in reality, they only do it for their highest grossing artists, if that. Or the artist could save up one or two thousand, buy their own equipment, produce whatever tracks they want, and get just about as much promotion and marketing from the labels as if they were signed (asymptotical to zero). So my question does indeed still stand. As far as your Eminem example, Eminem came out in the late 90's when self-production was not quite affordable yet and was just starting to reach quality on par with professional studios. He's also one of the most extremely talented rappers so comparing him to someone that isn't on his level easily explains the discrepancy between the two.
