Heres a great example of what I mean. I should mention that my wife works in healthcare, so she sees this everyday. https://www.healthsystemtracker.org/chart-collection/health-expenditures-vary-across-population/#item-out-of-pocket-spending-on-health-services-is-almost-as-concentrated-as-overall-health-spending_2016
In 2016, 5% of the population accounted for half of all health spending. The 5% of people who spend the most on health care spend an average of around $50,000 annually; people in the top 1% have average spending of over $109,750. At the other end of the spectrum, the 50% of the population with the lowest spending accounted for only 3% of all total health spending; the average spending for this group was $276.
