Most of his wealth being Amazon stocks makes this companies treatments of employees WORSE not better.
The fact that one person can steal so much wages from his employees while simultaneously also getting “paid” through their equity, and that stealing wages and wage growth from his employees is viewed as positive is everything that’s wrong with capitalism.
What does "hoarding" mean here?
Amazon's value is reflected in its share price, this isn't decided by one person or entity. When someone or some entity buys or sells Amazon stock they are deciding what they think the stock is worth. He owns a large amount of this stock because he founded the company.
Is he hoarding Amazon stock? Do you mean there is a finite amount of wealth and he has hoarded it somehow in Amazon !?
He worked to make his company as valuable as possible, which is what his job was.
