This was the attitude that made me not use the graphic design degree that I got and move into software development (other than the fact that I had been building and using computers since I was 12). People look at the arts as a "thing you should just do because you enjoy it". Can you make me a logo in your spare time is a common refrain. It seems to have trickled down to software development.

Anything anyone has a true passion for, eventually, will be seen as a free commodity by interested parties, unfortunately. I wish it weren't so, but business acumen and true passion are often enemies.
