Does it bother you that the productivity of the professionals on strike over pay is the hardest to measure? How do you measure the productivity of a medical doctor? The number of patients attended? The number of patients healed? The number of patents?
The best measure would be longevity. But here comes the paradox. The greatest life extensions in the last 100 years did not come from blockbuster drugs, but from improvements in basics like hygiene, clean drinking water, better food and sanitation. Think of malaria.
