Is bad programming a net negative? I'm not convinced (and it's not just because I'm a bad programmer, I swear!), I think if you only had good programming, you'd have very little programming and that would be concentrated of the areas that the powers that be deem most important: military, finance, police, factories.

Having bad programming gets you a lot of programming. I'd rather have a million people who can each build a house a day that will stand reasonably reliable for ten years than having a thousand people that can each build a house a day that will stand for a hundred years.
