Go to Georgia Tech. Major in Math. Minor in Econ. Can go to grad school for economics or other disciplines. Very employable. Could do the same at Carolina. Carolina honors is well regarded.
The extra $200k for Rice undergrad doesn’t really make sense unless money isn’t an issue.
S20 had very nice offers from our in-state flagships including honors. When he got into GT I basically said give me a good reason not to send in the deposit today. It was one school we were willing to go a little over budget. He’ll graduate in 6 semesters (knock on wood). He’s had an internship and a co-op that have paid well.
