There are a bunch like cable companies.
But, the worst is drug pricing.
There is absolutely no reason that 30 pills of a drug is $20 in Canada and $100 in the United States. It’s an international good like anything else.
And it costs us billions and leads to people having worse health because they can’t afford medications.
You couldn’t design a more bizarre medical situation then in America.
Ending monopolization on pharmaceuticals would be a huge move towards sanity.
