Why are prescription drugs unaffordable? Because of a grant of monopoly privilege called "patents" that allow a company to monopolize a drug for around 2 decades. Why is health care so expensive? Because the government subsidizes employer provided insurance through the tax code so nobody cares about controlling medical costs. Why is housing so expensive? Because local governments literally make it illegal to build housing infringing on the private property rights of landowners with idiotic "zoning" laws and by doing things like declaring run down parking lots to be "historic" parking lots that must be preserved. Why is the labor market so skewed against labor and in favor of capital? Because numerous government laws make it harder to start businesses than it should be and also because government subsidizes employers providing "benefits" through the tax code. Why did the railroads collapse and most of the US become dependent upon cars? Because the government regulated the railroads to death with the Interstate Commerce Commission and subsidized both cars and car infrastructure. You can keep going on and on with examples but the answer is almost always something that the government did to screw up the market.
