At the end of the day, as long as there are workers and owners (investors, CEO, etc.), and the company takes profits which they have not labored for, then it doesn’t matter. Even if a cashier is getting paid $100K with paid sick time, a “great” health insurance package, 6 weeks vacation a year, whatever else people demand at white collar jobs (but you never see at something necessary… like stocking shelves…) it doesn’t matter. If the company agreed to pay $100K that just means the worker earns them that + much more in value they’re creating.

This is just a fundamental fact that Americans, in particular, seem incapable of internalizing. Only workers create value. Owners aren’t workers (well, sometimes, but that’s a different discussion). That includes the CEO under owner. So any salary or compensation the owners receive is stolen from the workers. In addition, whatever salary a corporation agrees to pay will always be lower than the value the worker creates. (That’s just a “hard law” of how this works.) So no matter how relatively “great” the pay is, some hidden portion is being stolen.

(None of this is really directed at you. Just the type of person (specifically those in US) who will unironically “scold” Costco workers because “others have it worse.” Just gross lack of any solidarity, pure individualism, and precisely why nothing ever gets better. Part of the reason anyway.)
