Homework:
So here we go. First an axis for health, life expectancy, from 25 years to 75 years. And down here an axis for wealth, income per person, 400, 4000, and 40000 dollars. So, down here is poor and sick, and up here is rich and health.
Now I am going to show you world 200 years ago, in 1810. Here come all countries, Europe brown, Asia red, Mideast green, Africa south of Sahara blue, and the America's yellow. And the size of country bubble shows the size of population. And in 1810 it was pretty crowded down there, wasn't it? All countries were sick and poor, life expectancy was all below 40 in all countries, and only the UK and the Netherlands were slightly better off but not much.
Industrial revolution makes countries in Europe and elsewhere and move away from the rest. But the colonized countries in Asia and Africa they are stuck down there. And eventually the western countries get healthier and healthier. And now we slow down to show the impact of the First World War and Spanish flue epidemic. What a catastrophe!
