It is impossible to predict how your child's life is going to turn out. I know a bunch of people who are making great livings with degrees in supposedly "low earning potential" fields like art, English, etc. Some are web developers, some are medical professionals, some are social media experts, some are entrepreneurs, etc. Who knows what the future of the economy will hold.

IMO it is better for parents to stick to logistics and standards, like "this is how much we can spend on college" and "this is how hard I expect you to work."
