You need to stop to see the world in black and white. The Federalist Society is a corporatist / statist organization. They hate labor. They love big pharma, etc.
Centralized control over industry can have some pretty bad consequences too.
2) Once a megacorporation has established dominance in a given market, a combination of network effects and regulatory capture removes competitive pressures. This allows the internal planned economy of the corporation to continue without competitive pressures. See e.g. Google, which essentially throws money earned through dominance in ad markets against the wall in every direction but produces little of new value.
The reason my "capitalism" has quotation marks is to point out that actually existing capitalism in the USA has pretty much nothing to do with competitive free markets.
If a company goes above and beyond the requirements of the law and then removes that perk, I don’t see any legal issue with that.
As long as they’re not a monopoly, the option of working for another employer is a good way of combating legal, but immoral company policies.
Either way, talking about pay and unions is just as valid as talking about any other work activity.
