It should not be bizarre. Everybody should adapt and act accordingly, save money and keep your axe sharp. No job is forever, no employer is your friend or family.
What about demanding a salary no less than 50% of the value you add to the company? How many industries would stop being viable if their whole workforce would demand to be compensated for the worst case scenario Everysinglepaycheck? A couple years ago this would have sounded like hyperbole, but then the Great Resignation happened, so there's that...
From that point of view, severance payments are not noble handouts but compensation strategies to reduce the overall payroll cost.
Whatever country you moved to, odds are there's more of a brain drain from there to the US than vice versa. When places heavily regulate laying employees off, they just make employers much more apprehensive and conservative about hiring.
From a capitalist perspective, the paternal employer-employee relationship is one of mutual benefit. Ensuring that the the employee's incentives align more closely with their employer's. At the same time it acts as (an arguably weak) justification for corporate profit, a comfortable and loyal employee is one who does not concern themselves too much with where the rest of the money is going.
The idea of the relationship as transient and adversarial directly opposes this. When companies force their workers into precarity, while at the same time making record profits, there ceases to be a justification for accepting that profit in the eyes of the worker. Eventually leading to some kind of societal response.
