I agree. D1’s Ph.D was “fully funded,” but her stipend was nevertheless quite low in our opinion. We payed her rent for most of that time.
We are paying D2’s law school/MBA program at a private school. If we couldn’t, we wouldn’t and would feel no guilt about it, but since we can afford it, we happily do it so that she can start her professional life with no debt. I don’t see this as “touchy area” at all. JMO.
