I am not placing any importance on having alot of financial security. It is just that many musicians are well... homeless.
I know a large musicians guild here in Australia and none of them are homeless or stuggling to eat or keep a roof above their heads. In fact all musicians I meet make an honest living, perhaps not as much as a doctor, engineer or lawyer, but enough to live and continue working with their art. (And if you understand musicians, living to work for your art is more important than living to work for money security but this doesn't mean that we all ignore playing the money game.)
The thing is many musicians are self employed, that is they are not working for any institution. Owning your own business sets you up to be responsible for the money you make and the growth of your business. Unfortunately not all musiicans are business minded so when they try to go it alone they find it tough. It is nothing however that you can't learn, a musician might be poor while they start out, but we all eventually find our niche.
I do not see any difference between musician and any other job for this matter. We all have to stuggle to get somewhere, it is not as if musicians are all poor, just as it is not true that all painting artists live off governemnt support.
I think we have to define what makes a professional musician. For instance I know one guitar teacher who was a computer scientist but chose to take on giutar as a career when he lost his main job. Sometimes some people are musicisn to fall back on something and not be unemployed. These people are merely being musicians to keep the money flow going instead of being homeless!
I don't believe in luck communist

It's all about timing, being there are the right time, taking those windows of opportunity when they open. The more you are aware of opportunities the less you will miss them, the more you get lucky I guess!
