I'm also a musician and software developer but I don't agree that there are "less employment opportunities in the industry than at any time in the last 100 years." That is just ludicrously false. You're saying that, in the Great Depression, to pick an obvious example, times were better and easier for musicians? Or during World War I? Or WWII?
Sorry - I think this is the golden age for being an artist. Never before has it been so easy to record and distribute. I can self-record as many albums as I want today for $3000 worth of pro-sumer level gear. I can print physical copies of the CDs for $1.50-$2 each and sell them for $10 at shows or make $7 by selling them online. I can sell digital copies for $0 upfront cost to me. I can have a free website with any number of sites. I can post my events on Facebook at no charge.
I'm sorry - I 100% disagree with you here.
