@younghoss I think your comparing a 4th year of college to summer camp is off base. There is more to an education than taking the minimal requirements. Most kids graduate without getting to the breadth of their major let alone the opportunity to take some business classes or more foreign language or other knowledge that would make them more marketable in the long run. No one is advocating going into debt so your kid can go to frat parties.
My eldest had so many credits from duel enrollment she could have gone to an instate college with all her general Ed’s and graduated in 2 years at the age of 19. Thankfully, she got enough money from a selective LAC that she could take the full 4 years. We saw a huge amount of growth and confidence between 19 and 21. I believe her experiences those two extra years allowed her to successfully launch after graduation.
