In a healthy marketplace, customers stop using merchants that abuse customers, until they change their practices or go out of business and are replaced by more customer-responsive competitors.

Here in the US, however, 5 hotel brands have been allowed to control over 70% of hotel rooms nationwide. This means a dispute with even one will cause big problems for business travelers.

Same thing with Ticketmaster/Live Nation, Google, Amazon, etc.

This extreme consolidation of market power seems to me like a degenerate form of capitalism that breaks my libertarian idealism.
