@aeva @bruces There are no year markers on the other countries here, so it's hard compare where others were at the same time. But it looks like the US was spending more than the rest of the world for the same results already back in 1970. The factor may have grown from like 2x to 3x the average of the rest though, but the problem was there from the start of the graph. Would be interesting to look further back. But I'm most curious about 2014 to now.
