So if you actually want to work in a university or lab in your field, those can be tricky majors with lots of opportunity costs and uncertain prospects.
But coming out of colleges like Pomona, if you want to do something like business, law, government, health (assuming you also do the prereqs) or so on, you will likely have all sorts of prospects. In some cases after more education, but like law schools, say, love Math and Physics and such majors with really good grades and high LSATs–I mean they love all kids with respectable majors with really good grades and high LSATs, but not least Math and Physics kids. Same deal with med schools if you have high grades and a high MCAT (and did the prereqs). And so on.
Point being they don’t have to be limiting degrees financially if you don’t want them to be.
