Apparently Warner Brother's (and other's of the same) can produce and shelve a movie, and use it as a tax write-off. So if my taxes can prop up an industry that has the ability to "conveniently" shelve their works, while recouping a bad investment...why aren't their shelved movies "public domain"? We kinda paid for them the moment they became a write-off

If I paint on canvas, and decide to never even try and earn income from it; do I get to recoup my losses in supplies? Or does the "standard deductible" override my loss, and the tax-burden falls back (again) on the working class? Or I'm dumb and don't understand taxes, so please enlighten me
