Oh please, are you a troll?
No one in their 40s or 50s today studied how to market on the internet, yet many are doing just that. The value of a liberal arts education is very great. Learning how to learn and communicate sets you up for anything you want to do.
Plus the obvious - why would you want to set your son up to study something he doesn't do well in and doesn't enjoy? Sounds like a recipe for unhappiness to me.
