Doing away with large companies doesn't guarantee that this will end, though.

An example: while there are few large corporations providing physician services, the American Medical Association lobbies on behalf of the thousands of individual doctors and small private practices, often to the detriment of consumers anyway.

Also small companies often employ and are owned by my neighbors.. Amazon doesn't and is owned by a bunch of hedge funds and a dude who buys $200M houses.

Large companies also employ my neighbors, and clearly for a better value as otherwise they would be with smaller ones. As for ownership, Amazon is part of the S&P 500 which is quite literally owned by millions of folks in their savings, 401k's etc. Hence the reality is not that simple.

And plenty of small investors like me own Amazon via their manged funds
