making a living off the arts is like winning the lottery.
There's too much free/discounted stuff out there for the masses to want to pay top dollar for something that can be easily acquired for free.
Just because there's free art out there doesn't mean that's why people aren't buying. I don't buy CDs or books because I find them inconvenient, but that doesn't mean I'm replacing them with something that's free. I don't buy paintings either, because I don't find them interesting. In fact, there's a lot of 'art' (be it a painting, book, film, photograph, song, poem, etc.) that gets produced that nobody finds interesting. The reason it's hard to make a living as an artist is the same reason it's hard to make a living as an actor - many people try, very few people are actually any good at it. I'd bet that more than 99% of the art that's produced each year couldn't be given away for free. Just because an artist likes their own work doesn't mean anyone else would be willing pay for it, no matter the condition of the market.
Marvelous! The super-user's going to boot me! What a finely tuned response to the situation!
