I agree with part of this. Yes, there are many sides to the music business and many people involved with RELEASING a record.
With that said, the artists do THE MOST in any situation because they make the records that allow everybody else to eat. Without the artist, these businessmen would be washing cars or doing some other shit.
Artists make the record (countless hours in the studio, late nights, etc.), tour for months on end to promote the record, miss their families, birthdays, and holidays. And how are they repaid? They get a PORTION of their publishing (If they are lucky), a small percentage of record sales, and all the stress of making a hit record so their contract isn't ripped up.
Businessmen write the checks and then collect heavily after the fact.
No, many artists are not business savvy...but they are the creative minds that put more money in the pockets of others than they do their own. They do a lot more, and miss a lot more, than anybody else involved who sits in an office and gets to go home every night.
Artists, producers, and managers should be the ones getting the big checks.
