Also assuming that your parents won’t pack up and move again right after you graduate college, they will face this higher cost of living and taxes looking towards their retirement years.

I agree this plan sounds very shortsighted.
The UCs are not the be-all, end-all of colleges.
Some kids can’t even get into Texas unis because they are OOS and wished they could.
