University of Bocconi vs UCLA

Hi, I am confused about whether to go to Bocconi (60 L for 4 years) or UCLA ( 2.5cr for 4 years). While my parents can fund both, I would prefer not to drain too much of their money. If I go to UCLA they would not be able to fund my MBA. So I want to go the uni which will maximise my chances of getting a good, high-paying job. My major is math and econ and I wish to break into consulting/investment banking.
