For fun, what activity would you say is ridiculous to “do online”?
Not every child can afford to go to a good four year college. Simply because yours did, doesn't mean everyone can. You do what is within your means to generate the best outcome available. Finishing your college years with a mountain of debt that you will be paying off for half of your working life is not my idea of a good plan. Looking down on someone who is less able financially to send a child to college for four (or more) years is not an attractive quality in a person.
