Post-communism, the economies of the Balkans have grown rapidly but populations have collapsed by 20% - 30%, with no end in sight. These are also the most rapidly aging nations on Earth.

As a highly-vaccinated cardiologist, I cannot believe that anyone could accept such an absurd claim as that made in this paper. A 76% reduction in MACE would make covid shots the most effective cardiovascular therapy in human history. This is just magical thinking and an illustration of the uselessness of this type of biased and confounded retrospective analysis. Another illustration of the epistemic crisis that medicine is in today.
The only thing wrong with this analysis is the assumption that the liberal capture of the education system is effective in converting the children of conservatives: on the whole, it is not (as seen by the fact that 81% of children of conservatives become conservative).
