Do you know how sharp the fall off in income is as you move down in popularity from "Guaranteed Billboard Chart Topper"? I suspect by "career" the GP was referring to financial success, which, if you're an ugly woman, is almost totally impossible (Something that's not nearly as true for ugly men).
Yes, thousands upon thousands of people still make amazing music with very little concern for profit (and I'm as grateful as I suspect you are for their passion) but they do it for a pittance based on love of the craft.
Music is not limited to the payola crap pumped on most stations you know
And I'd say it probably gets better with music sharing over the internet, the ones complaining are usually the executive heads.
