Of the examples you listed, politicians are the only ones you directly fund and supposedly work for you. Your lawyers and doctors aren’t your employees, and they also don’t work on your property (though lawyers might handle your documents). The biggest thing this points to is that the mask is almost entirely off between employee-employer relationships in the US, and it looks like by ensuring everyone depended on employment for insurance before turning this corner, there’s not much resistance left.

This is why a worker's rights movement is important. You shouldn't have to rely on your employer's goodwill. Reasonable privacy rights on work equipment should be guaranteed by law, and any large company should have a Euro-style worker's council.

The legal environment is the only way to baseline behavior. In countries with strong worker's rights, you generally don't have to fight much to make use of them; it's the norm for management, too. Likewise, the US-style norm of having no expectations toward your employer and the "stay in your lane" type takes rampant in the thread are also symptoms of the environment and its norms.
