This entire diatribe about stock buybacks makes 0 sense. It's just another way of returning money to shareholders, it's exactly the same thing as dividends but gives the shareholder the option to realize their gain. A business
only exists for the benefit of its owners, if businesses negatively impacted owners, they would not own shares in the company. If employees want to enjoy the benefit of being owners of companies they can start their own companies or themselves use their income to buy shares in companies. They will quickly realize that starting a business is really fucking hard.
Before you mention monopolies, yes I agree and I think what Lina Khan is doing is great and she should be doing more.
Also, just because you don't understand or disagree with the logic economists use doesn't mean they are wrong. Stick to writing bad fiction please.
