Abundance only solves scarcity if scarcity is the problem, but the actual problem is economic exclusion, which will always be able to outpace abundance because abundance has physical limits while exclusion does not.

Scarcity of housing is a severe problem, one that has caused the economic exclusion by preventing new people from entering the locations with lots of jobs.

It really is housing and scarcity at the bottom of all the other symptoms we see.
