I think the issue is that many people see monopolies as a good thing, as long as they are not being very blatantly abusive (and especially if you can say, "well look, they only control 80+% of the market!"). Examples: Thiel, Friedman, maybe there are others. The march towards efficiency, productivity, and profits naturally cuts into redundancy, diversity, and competition. Same goes for index funds, holding companies, etc. I wonder if there is any way we can find a balance, because it seems like there are so many cases where giving up some efficiency/productivity for some other traits is desirable (renewable energy, research and development, health, safety, etc.)
