In some Europeans countries like Finland and Denmark I see this being the norm.
The cruelty is the point in America. These companies know all of this, they pay people to study these things internally and give reports. Having a certain level of money and power over people rots your brain. When you're presented with rational options, you'll ignore those options and continue doing what you've been doing that doesn't work because you haven't been made to experience the consequences of your behavior.
If an alcoholic has an unlimited budget, he won't see his alcoholism as a problem. It's not getting in the way of his work because he's independently wealthy. He isn't at risk of losing his housing because he owns it and his bills are all autopay. Sure his home literally looks like a fukking garbage dump, his body is disgusting from neglecting his hygiene and his liver is a ticking time bomb, but as far as he's concerned everything is okay. He is not feeling immediate consequences for his addiction so he has zero reason to change.
Wealth in america is similar. If you were a rational capitalist and not one whose brain has been melted by excessive profits to the point where money is meaningless--you would be in favor of whatever helps your workers stay working, keeps them happy, and keeps you paid. In America though where Capitalism is being left to run rampant, you suffer from wealth poisoning, gain a virtually unlimited budget and stop making rational decisions.
If there is a higher federal minimum wage, this allows more people to afford products and services--They oppose this.
If there were unions, skilled employees would remain in the company for longer since they'd have more protections--They oppose this.
Shorter work weeks would mean more time for people to go out and spend money on products and services--They oppose this.
A public option would mean companies spending less on offering health insurance--They oppose this.
"I'm a capitalist, but I oppose measures that would allow more people to participate in capitalism"
"I don't care how much harder the frontline employees work. I deserve more money as an individual than 10 of them make"
Those two thoughts basically sums up the average mindset of a manager in America. It's completely irrational and only makes sense if you have the mindset of an addict who needs to get his fix. "enough" is not a word that exists in the vocabulary of an addict. I can't have enough alcohol in my blood. I can't inject enough heroin. I can't sniff enough cocaine. The only thing that makes an addict stop consuming their substance of choice is when they physically can't consume any more or are made to stop by a third party. The European union and some countries in it are like a bar with a bar tender and security that will cut you off and drag you out when you've had enough and start getting belligerent and really for your own good. America is a bar where the alcoholic has a gun, the bar has no security, and the bar tender has to keep pouring up or else the alcoholic will shoot him and just drink everything in the building.
