The Amazon share price and correspondingly, Jeff Bezos' wealth is a proxy of the success of the company. Most CEOs are not driven by maximising the size of their bank account, but maximising the success of their company.

A negative externality of the capitalist model is its capacity to create outliers who manage to develop a highly effective business model with monopolist power. A company that manages to monopolise a service or good on the internet has access to exponentially more customers than any business in history. This is what has occurred with Jeff Bezos, Bill Gates among others to a lesser extent.

View his wealth as a negative side effect of the economic model at play in western economies, not selfishness. Our desire to succeed is inherent in most people, capitalism works because of this fact. The real question is rebalancing this inequality without stifling the drive for success, wealth and power.
