More proof that CAPITALISM is the main driver of improved life expectancy 

I've compiled plenty of proofs re: this but here's one more.

Child mortality had dropped in the UK to less than half by 1800 - WELL BEFORE EVEN THE THOUGHT OF SANITATION HAD ARISEN.

NOTHING but capitalism can explain this. And since capitalism has a very long tail (as more and more people become rich), I'm very confident that 80% of the improvement in human life expectancy can be attributed to capitalism.
