By "the West" I mean Europe west of the Iron Curtain, the United States, Canada, Australia, and New Zealand.

By "rich" I mean that the median inhabitant of the West should be richer (enjoy a better material standard of living) than the median inhabitant of the whole world.

Whoever resolves this market (the actuaries seem to think I might not) will do their best to resolve it based on publicly-available statistics at the time. For example, "standard of living" might be measured by income, which might be estimated by per-capita GDP. It's not clear how exactly to determine the median person's income, but I'm sure when the time comes the market resolvers will do their best.

(As of right now, I think any sensible attempt to answer the question would determine that, yes, the median inhabitant of the West is richer than the median inhabitant of the world.)
