OT - Music Business Questions

Does anyone care or have questions about the back ground of the music business? I'm curious, especially watching all those Behind The Music's that were on and how a lot of musicians became broke after making millions.
For example, one of the questions I was always wondering about is, who pays for their (each band member) health insurance? Does the record company? The band as a business? Themselves?
If a "roadie" is working for a band like Styx, who pays their paycheck, do they have health insurance? Etc. What about flying to concerts and meals?
I know that a few musicians are "self-employed" and they have to pay their own health insurance.
