Nobody is saying finance people should be poor and starve. The same people critiquing the finance industry in this thread have been happy to critique ad tech as well, and I agree that they're both largely parasitic 'faux frais'. But regardless of which industries you choose to put in that category, the point isn't to make individuals choose to work in one or another -- that's not how serious change happens. It's to build support and hopefully eventually consensus on the idea that our economic system is broken and in serious need of change.
