Great comment. And really, neither one is right; they're just different.

Also, even from my western perspective, I can see logic in both positions. Programming certainly requires more skill than janitorial work. On the other hand, it's more inherently rewarding as well (at least to most people). So even outside of cultural biases, if there's sufficient highly skilled labour available, it makes sense for pay rates to equalize (and eventually for less desirable jobs to be paid even more than skilled ones).
