Yes, we are all slaves to something or other. Even the president of the good old USA.
I think that in today's society, and in most parts of the world, many individuals have been sucked into the idea that unless they are "somebody" then they become a no-body. Sad really.
I take your point about the music business being fickle, but then again, so is the film industry, television, sales, politics etc, etc. When people are down on their luck or aren't performing consistently, they tend to be dumped pretty quickly.
At the end of the day, it comes down to the individual and how honest, compassionate, and honourable they choose to be. Most times, the pressure of business wins, and the outcome is more often than not, at the expense of someone who is nameless to them.
