I've been reading S.M. Stirling's Change series lately, which begins with the book:
The premise is that in 1998, something happens around the world which eliminates all of Earth's high technology, particularly electronics and explosives. It's alternate "history," with both utopian and distopian elements.
But reading the series has had me thinking about wealth.
See, in the Dying Time that followed the Change,
very few people in the cities survived. All our stockbrokers in New York? Turned cannibal and/or died. Wealth did not necessarily mean survival.
