> The income potential of these fields is known, so complaining about this, once in the field, is really just an irrational thing.
Are we not allowed to complain about known things? If you get a speeding ticket do you complain about it? Under that same philosophy, complaining about your ticket is irrational and stupid. Someone complaining about a hangover is irrational and stupid. Someone complaining about having back problems because you sit all day and don't exercise is irrational and stupid. I just don't think this line of reasoning makes sense at all. Our priorities change and maybe a teacher wants to do something good for the world but after 10 years they see they're not paid/respected well, and they have a family to take care of and a mortgage to pay and they're tired because they work 60 hour works. IMO that's a very rational place to start complaining.
