I think you'd be surprised that top tier talent (and people in general) usually don't worship money and aren't willing to degrade their standard of living for an extra 75k annually after taxes.
I suggest you update yourself on the monetary incentives/benefits for employees that US frontier labs provide. 75k is a drop in the bucket of the amount of money those employees gain in an IPO event, let alone bonuses.
A lot of us already make a lot of money. It’s not about the money. It’s about the work. I would love to work on the things OpenAI is working on. I don’t expect it would be much of a pay raise. But I’m not moving my family for it.
