"Source: The U.S. Census Bureau American Community Survey (data)". FTFA. You don't even have to read it. It's the source for the first graph. The one blown up before you even have to scroll.
The first erroneously said the US doesn't track it, but the next two of you didn't read the rest of their post.
It's clear to me that they were just looking for a launching point to complain about capitalism and didn't really care where that came from.
They absolutely claimed the latter.
But even to the first, they didn't make any policy claims! They said it "would clearly show how poorly the economy is actually functioning." That's not true! You can have a fabulous economy (with a well-performing "GDP or...stock market") with terrible healthcare KPIs, this is basically a petrostate.
Healthcare is measured. And it's discussed. One can debate how the total-insured figure should play into policy. That wasn't that comment.
