Minor nitpick, I agree on the other points but Spain objectively does not have a "far worse" Healthcare system than Sweden in 2020. You might need to revise your assumptions.
Looking at the data available up to 2015, Denmark already had a worse HAQ index than Spain in 2015, and Spain had a negligible difference compared to Sweden [0].
Spanish longevity has kept increasing and competing with Japan [1], beyond 'mediterranean diet' effects, which again many attribute to Healthcare quality.

Also, I think there are a lot of problems when conducting comparisons between countries, and it is best to be avoided unless conducted in a extremely rigours way. There are absolutely ways ways in which Sweden is more like Spain or Italy than Denmark or Norway, and it take a through analysis to even attempt a comparison.
the fact is Sweden is still doing far worse than Norway and Denmark
