Large companies, like cable providers for example, make agreements with each other to split up the country into their own regions and charge whatever they want. Things like internet access have become necessities and should not be unaffordable to anyone. It’s time to start trust busting like Teddy Roosevelt and prevent these monopolies from over charging people.
Additionally, mega corporations should not be able to venture into types of businesses where they can put other companies out of business. For example, if Amazon wanted to wipe out paint stores, they could use their massive industry wealth to create a monopoly in that space.
Also, the Starbucks model of overflooding the market to chase out competition should be illegal.
