One of the ironies of this effect is that if you magically reduced the American population by, say, 50%, we'd probably see
increased crowding, as maintaining the intricate systems that permit suburbia and rural-commuting would become prohibitively expensive. We'd end up with more people packed into the cities.
OTOH, in many ways it's easier to police and provide services to dense populations, so the life in those cities would not
have to be
Bladerunner redux.
