I am going to share a little analysis I’ve done by combining Pennsylvania’s PSSA test scores, Census ACS data, and Department of Education statistics to refute a few popular progressive notions about education, namely, that:

UPDATE (9/25/2016): I just created a new and (hopefully) much improved version of this argument here. I suggest you start there instead.
Numerous people have asserted that the United States spends dramatically more on healthcare than other countries, presumably even more than countries of our level of wealth and affluence, and that this can only be explained by the fact that we do not have single-payer or some such.
Here are some examples graphs used to make this point
These appear to be very convincing at first blush, but i never found these arguments particularly convincing due primarily to:
- Imperfect comparability between the selected countries
- Issues relating to comparing countries of the “same” GDP
- cherry-picking of countries
I knew the proponents of single-payer were, at best, making an incomplete argument and that it invited an exaggerated impression of what we should likely expect from a country like ours, but, up until now, I lacked the data and the time to present these argument comprehensively. I recently got in an argument with someone over this subject and found a treasure trove of data all in one place (mostly) to thoroughly debunk this overly simplistic argument.
To make my points, vis-a-vis fundamental issues with naive treatment of GDP per capita and sensitivity to comparison countries, here is a quick chart showing National Healthcare Expenditure (NHE) as a percent of GDP by GDP per capita
