I don't agree that we need "less liberal arts degrees" but having more stringent STEM courses that push students to excel is never a bad thing. Bill Gates used to say "smart people go where the money is" and so if by the author's assertion that the new economy needs people who are good at math, then the market will reward those people and the system will change to focus on math skills. This does not mean that liberal arts degrees are useless as the best innovations usually come at the intersection of liberal arts and STEM fields.
