The roadblocks to these laws is that they don't come for free, and loads of businesses would either no longer be viable or would be able to hire less. This is one of the ways that Amazon is building out its moat to prevent challengers (note that Amazon has had a $15 minimum wage for years). Of course there's a happy equilibrium somewhere in there, but this is not the role of Jeff Bezos (or my hypothetical sandwich shop) to figure out.
I expect my government to determine the rules of how society can function, and I expect businesses to be as efficient as possible within the bounds of those rules.
As an aside, though, none of this has to do with the concept of someone being forced to give up their own company. If a company needs to act a certain way, then the law should force the company to act that way for sure. If a company was following the law, though, the backlash for crappy outcomes falls firmly at the feet of that law.
Workers should share in ownership. If the value of the business goes to zero, their ownership stake goes to zero, just like the founder.
It's very unlikely that you personally, singlehandedly would be able to build your sandwich shop into a billion dollar franchise.
The value of Amazon is not a trillion dollars because of Jeff Bezos alone. He helped get it there, sure, and he deserves to be rewarded for that, but so did 800k other people. Can an Amazon driver afford a house, 2 cars, and to put 2 kids through college on a single income today? My dad could working for UPS for 30 years starting in the 80s. He's retired now with a pension. Why can't Amazon provide that kind of life for their workers? They're certainly richer and more profitable than UPS ever was. One key difference is that UPS is unionized, and then you start to realize why Amazon really, really, really, doesn't want their workers to unionize.
Bezos' wealth is not a problem in a vacuum. It's a problem in a world where he's using his wealth to fly to space, while others (even people who work for him) are being evicted from their homes during a global pandemic, and there are more than enough homes to house everyone. That's the backdrop for all of this outrage.
IMO an example of what would be incredibly immoral is if your ownership stake in your national sandwich chain reaches $1 billion, and your workers aren't making a living wage that can cover rent, food, and healthcare for their families. Yes we want to encourage entrepreneurship, but we cannot do so at the expense of workers. I think we've gone too far in one direction and now the backlash is forming.
