I get where you're going with this... and I'm not in favor of monopolies and anti-competitive behavior... but Amazon is a hugely innovative company, and I do not believe that they've merely consolidated wealth without creating any. Think of just AWS as an example and all of the companies (and their employees) who've created more wealth as a result of it.
It is important to realize the effects that this consolidation has in terms of wage stagnation [1]. This is a very real effect that is felt by a very large percentage of the workforce. By consolidating wealth (and power) in the hands of few large companies those companies are able to pay a lot lower salaries to their employees. If your options are (1) work for Walmart for a low wage, (2) work for Amazon for a low wage, or (3) starve, you will accept whatever wage Amazon or Walmart will offer you.
In other words, as a direct consequence of these multinationals and their mode of operation, millions of people are getting lower salaries today than they would have gotten 50 years ago (adjusted for inflation) whereas overall productivity has gone up significantly. The difference is pocketed by executives and wealthy shareholders of these companies. As a result of those lower salaries, those people are now having trouble paying for core necessities (health care, education, housing).
This is the rising wealth inequality that people are talking about, and the rising wealth inequality that people want to fix.

Amazon doesn't "simply" take others wealth. It wins by providing a better service

And offering new, but delivering used, damaged products to customers:
There is an essence of truth to that, but it certainly does not tell the whole story.
Consider what happens with Amazon. When they put a family-owned store out of business, those people need to work somewhere. They then turn to the only place left that has any jobs in their area: the Amazon fulfilment center. They then get a minimum wage job there. It is clear those people have directly lost wealth as a result of Amazon.
In some cases the "creating wealth" argument holds up, but in reality what is mostly happening in the age of globalism is wealth consolidation, not wealth creation. Amazon is not creating new wealth, they are simply taking all of the customers and wealth away from all of the smaller businesses and consolidating it into a single huge entity.
This obviously has strong negative consequences for the people who are losing wealth. There is a reason wages have remained stagnant for over 50 years while corporate profits keep on growing to record highs.
