No need to be so absolute no one is "assign[ing] responsibility for your well-being to others", there are grey areas and gradients and employment is fundamentally full of those.
No one person can be an expert in everything, we live in a society and should act like it. Needing to be an expert in healthcare, hiring processes, finances, and a dozen other topics just to switch jobs is a major barrier to the just switch mentality you are presenting. And I know first hand, I am just switching constantly because it is what I wanted. We should have reasonable baselines and minimums for treatment, and those should shift and get better as we improve society.

Yet there are countries that have better situations for labor than the US?!
Even something as simple as universal healthcare would fix a ton for millions of US people. It would empower worker to switch jobs and employers to lure top talent held by it. Only a hundred or so other countries figured it out, there is no way we could do it here we would only end up disappointed, right?
I pick that as an example, but we could go over many possible topics that aren't blanket assignments of "responsibility for your well-being to others". Consider non-compete clauses, IP transfers, minimum wage and tons of other topics that if they had a minimum floor of decency could allow more freedom the the worker and employer.
