The thing that gets me about all the comics artist tragic endings is that these people don't seem to realize that there other venues where they can make money with their artwork besides the long underwear pamphlets.
You're right, of course.
But many of these guys want to draw comic books. That's what they love. They might go into advertising or some other field if they absolutely have to (and some have), but they're not happy about it. I can understand that.
Also, by the time some of these pros get kicked out, they're getting up there in years -- age 50 or older -- and it can be difficult to break into any new field at that age.
