poor and sick vs. healthy and wealthy

According to the late, great Hans Rosling, things are looking up.

Professor Rosling gave us a unique visualization of population and income trends over the last 200 years, and he came to an optimistic conclusion. In his words, we have become "an entirely new, converging world," one where "everyone can make it to the healthy, wealthy corner."

Some of today's discussion centered on that assertion, with many of you agreeing that "aid, trade, green technology, and peace" will carry the day, with others noting the continued presence of war and the diminishing success of green technology making the future look less rosy.

In any case, I'm hoping that the concepts we are learning continue to spark thinking about the world you are inheriting from us.
