Probably because our lives are so cush. A lot of liberalism is built around guilt, that feeling of having more than you deserve. And in the world of tech, with our free drinks, free snacks, complete lack of dress code, upper 50% pay largely for doing stuff we’d be doing anyway, plus the quantity of time we spend not doing anything, game rooms, frequently short days... It’s really easy to feel like we’re rewarded in excess of our contributions.
This. I've asked friends in tech how they can support socialism, confiscatory taxes when the money is just pissed away, and they basically say (I) I can't spend what I make anyway, and (II) I would be doing the same thing at home anyway, it's my passion (III) They are so insulated from the real world they believe they are helping the little guy by supporting socialist programs
