In the music world, the word "Support" seems to mean to clap, smile, dance, and enjoy. Everybody "supports the arts" and "supports musicians," because it feels good to say it.
Although appreciated, this limited definition of support does not enable musicians to pay their bills or devote their full attention to developing their craft. In fact, musicians, especially those who work in clubs, are commonly expected to have other jobs in order to support themselves, often at menial jobs.
Perhaps the saddest part of this is that experienced, talented musicians are forced to stop performing, while a new crop of amateur, startup (e.g. free) groups parade through every few years -- aka Fresh Meat.
