If only there were some sort of legislation designed to reign in monopolies, duopolies, collusion, and business practices that prevent competition :)

You know who doesn't have a monopoly allowing them to charge whatever they like? Netflix.

Based on US ISP profits I'd say there is practically no regulation and they even split up the market so there's no competition so most consumers only have one choice.

Netflix competes with all the other streaming services no? If they increase the price too much people will stop subscribing. Or is your argument that they and other content owners should be forced to sell their content to all other streaming services?

There's plenty of antitrust laws already on the books. It's just a matter of enforcement.
