As an EU-based employer, I'm seeing a post-WW2 soviet vs usa style defection of engineers between USA and Europe. By the way, if anyone US-based is in this situation and wants to "defect" to an EU-job, send me a message, I can help you.
Not many will take a massive pay cut only to pay more taxes
Sure, in America why would anyone move from State A to State B to get less paid and pay more taxes. The social conditions are (in a wide-stroke) the same.
This is ofc not the case if you move to say, Europe or SK/Japan. The amount of money you need to live a similar socio-economic lifestyle is different.
And we already know that many people don't put certain value to increased income past a certain threshold (people want to feel safe and well-off; not necessarily be a millionare). We are in the HN/US-Tech bubble so ofc it feels like "everyone want to be the next Zucc with their startup" but if you once leave that bubble, you'll notice that most people are not a over-fitted model to one metric called income.
