Yes! One thing that would be pretty likely to work is radically changing our city layouts, patterns of settlement, methods of commute, density of living, food quality, food prices & price structuring, worker protection & time-off laws, and a bunch of other stuff. In the meantime (so... indefinitely, because moving the needle on one of those things would be the work of a lifetime) we now have drugs that can do it.
