This is absurd. The reason to go for a degree with a quantitative focus is because its much more enjoyable to read philosophy and psychology on your own.
A lot of people are well read in these areas outside of college. In general though people don't sit down with a PDE textbook for fun.
Personally, I would get a math BS with a minor in business or econ if I had to do it over.
