Consider the flip side of your suggestion: If you make money when the program works, that also means that you don't make money, or you make less money, when it doesn't. The last thing I need as a programmer is for a poor management decision to put me in a situation where a bug can be blamed on me and I can get my salary taken away.

It's also a bizarre idea that your programs won't have so many bugs if your workers have healthcare. (I'm also skeptical that many programmers who are employed don't have healthcare in the first place.)
