Source article: https://www.aei.org/carpe-diem/chart-of-the-day-or-century-8/ Several of the comments here already mentioned one of its observations: "The greater (lower) the degree of government involvement in the provision of a good or service the greater (lower) the price increases (decreases) over time, e.g., hospital and medical costs, college tuition, childcare with both large degrees of government funding/regulation and large price increases vs. software, electronics, toys, cars and clothing with both relatively less government funding/regulation and falling prices." Another good one is "The greater the degree of international competition for tradeable goods, the greater the decline in prices over time, e.g., toys, clothing, TVs, appliances, furniture, footwear, etc."
