I agree with you to some extent, however, the skillset you can build working for a financial institution motivates young adults beyond prestige. The knowledge you accumulate in these roles (info on investment strategies, financing options and strategic thinking surrounding exit opportunities or inorganic growth pathways) can be applicable in many industries and is useful no matter what you choose to do since money is moving the world. People prefer these careers for more than the high status and tech graduates could benefit from expanding their horizons.
