A few, sure. But plenty?
Even inside the US, that's a very small niche that's present mostly in a few places like in SV, Seattle and NY (I'm sure there are a few more, but you get my point).
The startup world is more about connections than hard work or competence. How many ridiculous startups get money because they have connections with VCs? How many very good ideas never get funding because they aren't in that circle? How many startup founders are 2, 3, 4 startups in and keep failing up? And those who can't bring those ideas to life because they work 2 jobs to sustain their families?
There's more than an order of magnitude of hard working people that will never even get a chance of becoming billionaires compared to the lucky few that were in the right place, at the right time, with access to resources and sometimes were even hard workers (this one is not required, despite the myth).
Meanwhile I've met many incompetent people that hardly work and are still successful business owners and millionaires because... they were already rich.
It's how the world works today. Maybe it'll always be like this, but I like to think we can change it.
> Offering people jobs which they can freely accept, reject or negociate is not exploitation.
Yes, it is if you're the only shop in town. If you can't leave the poverty treadmill because you can barely afford rent after working these ridiculously low salaries. I could go on.
I find it appalling how so many assume that people working in the Amazon warehouses are full of opportunities everywhere and they choose to work there, so they can't complain. I know we're mostly software engineers that are well paid but we could make an effort and put ourselves in their shoes for a second, couldn't we?
No, it's not black and white like your comment is claiming it is, and it never will be.
There's a big difference between choosing to pay the lowest amount possible without having people literally starve to death and a decent living wage. There's still a ton of exploitation that turns into profit for the few at the top, but they could at the very least treat people like... people.
If Bezos (or any other billionaire) chose to reduce their profits a few percent points, they'd already be able to provide a much better life for all of their employees. In my book, even putting the profit debate aside (exploitation of labor), that's exploitation in the moral sense too.
