Even better than getting "loans" from your parents is getting "grants."
Rich parents puzzle me. One would think they would say, hey, I will pay for your education as long as it seems productive forever, but after that, you don't get a dime baby, and the estate other than for some modest amount will all be going into a foundation or given to charity. Don't plan anything around an expectancy because it just won't be there. What rich parents do tend to do in my experience, in an unfortunately high percentage of cases, tends to leave their kids a dysfunctional sense of entitlement mess.
I don't think opebo would like me too much as a parent.
