Without questioning you specifically, I doubt any substantial number of others would feel the same. Few would pass up a even a 20% pay bump for the same role, so forget about it if it’s a 200% bump.
It genuinely depends on the person. In some places, WFH policy difference can alone amount to 10K difference not spent on childcare or traveling. You might be right on average, but I would assume most people do basic internal calculus of whether the move is worth it.
For me, knowing Musk's reputation for demanding workaholic mentality.. %20 might not be enough and that is before WFH issues.
>> Twitter would have to pay me something like 3 times more than Stripe for me to consider it, if I were back in the market and had those two.
Twitter was a public company with quarterly vests where you could get liquidity on your compensation (and from what i understand you were cashed out at buyout.) Stripe remains private and much of your money remains locked. Not sure if they issue RSUs, options, or what, but quite possibly you lose a lot or your historical compensation 3mo later. They were two different beasts. (Of course, now both are private, so going forward they might be similar.)
