Restore net neutrality. Force internet providers to share their networks with competitors. Internet is not a luxury, its a utility necessary for daily life just like electricity.
In theory, and only in theory, does a free market get consumers the best goods at the best prices when it comes to massive corporations. Telecoms are some of the most hated companies in America (according to basically any real survey taken by any source at any time in at least the last 10 years), for good reason. They’ve systematically used money and influence to reduce their competition by dividing up the territories they operate in. In most cases, you only have a single choice for internet service provider. Imagine if your only choice decides they want to charge you more. What are you going to do, stop using the internet? This isn’t in the realm of theory either, these companies already pursue means to keep their prices high and really don’t have much incentive to provide good service.
