What I’m saying is simple math. I would much rather make more than twice the equivalent worker in the EU and take the chance of a layoff. I can afford to have my own emergency fund to survive the gap in employment.
Every employee in the US is “at will”.
Lots of people, when evaluating the risks of contracting vs employment, find the reward far outweighs the risk. It sounds like you'd be one of them if you were presented with the same choice. And that's a fine decision for you to come to. But that's not going to be the same conclusion for everyone.
