I don't know if there's ever going to be a 'big money generating machine for future artists' that works as a template.

I'm guessing what happens is there will be many more artists making a little bit of money with their art, than in the past. People that would have never dreamed of making one red cent on their music 15 years ago can now make a little 'walking around money' through CD and sticker/T-shirt sales at local shows, CDBaby disc and download sales, etc. And maybe that is the way it should be.

Several different business models have existed over time for making money as an artist or writer.

Back in the really old days, one was selected as an artist and placed into basic servitude at the behest of the 'owner'. I don't like that model.
Then, later on, commissioned works, or (can't think of the work) all of the work that went into finding a benefactor to fund the mass production of your book/art. I don't like that model.

Recent modern times: Had to get a 'record deal' which was nearly impossible, and the artist's take from that was pennies on the dollar. I don't think that model works for most folks.

Make a little money on self-made CDs at the local coffee shop. Sell some T-shirts and stickers that you can get made up at cafepress.com. Make a few hundred bucks a year while still enjoying the hobby. Now, that I like.
