Why am I not making movies?

I have two questions arising from this chart. The first is why is any horror movie ever made as big budget? You'd think the studios would start a scholarship fund and just hand out $20k grants to film students and art school types. Cheaper than what they do to make horror movies, and if only 1% of them en up being good they still make a ton of money.

The second questions, is why aren't I making a horror movie?
