I don't like the idea of millionaires who make bad decisons being bailed out either, but it's not clear that is what is happening here.

Firstly not clear that this is really a bail-out in the usual sense. No tax-payer money is going to these millionaires, and any costs (if there are any, which isn't entirely clear) are going to go to other banks and their shareholders.

Secondly not clear that depositing money in SVB was a "bad decision" - doing this wasn't a risky thing VCs did to try and get rich.
