I am not arguing on the merit of having a diploma is a bad thing - the colleges these days have turned their backs on the people as well.
Average $100k to get a piece of paper (LLMs are not the issue here the useless degrees that the colleges offer). Invest that $100k at an average 15% return - it becomes a lot of money 25 years from now.
Or get a piece of paper (if your major is useless) and pay the banks 100k + interest.
