People seem to pay you more for stuff they are unable to do or just have the feeling that they can not. That might be the reason social work gives you a low income for a very hard work. People think they could also do it and no special qualification is needed, so they think the payment is OK. In tech, most people think it's witchcraft and pay absurdly high prices for support.
@Bobo_PK Hm, interesting point of view. Might explain quite a few things.
