I read this article when my oldest was about to head to college. We didn't have the money to pay for her anyway, but it convinced me we needed to set the expectation for all 7 of our kids that they would be responsible for their own future education/learning/progress. We encouraged good grades for scholarships and saving money for college expenses and stressed that those behaviors were all about putting in the work for their future selves.
I would say that in general it has worked well for us and for them. I'm sure they would have preferred that we do more. We let them take a lot of food whenever they come home and we might take them shopping when we go visit them, etc. We've also helped here and there where they needed money for a new car tire or something like that, but in general, all of them have figured out how to survive, thrive and get at least some education without depending on us in any way, other than emotional support, love and life advice.
I understand that a lot of people see it differently, but having raised 7 kids, I really believe setting the expectations that they are in charge of their own destiny helps build stronger, more resilient and self-sufficient young adults.
