If someone has consistently chosen to favor cash over anything else, that's a different story, but if someone chose an industry or type of career with money as the deciding factor I don't think that is terribly important. People need and want money.

If I don't know what to do and have no guidance, how am I to decide? I'll look at difficulty, social benefits, moral impact and economic benefits. A 20 year old won't necessarily understand how to parse difficulty, social benefits or moral impact but will absolutely be able to understand basic economic benefits, so I think it's appropriate to use that as a method for choosing a career direction and I wouldn't object to hiring them.
