I already mentioned the problem of masssive wealth gaps indirectly. Us workers need to organize to recapture the profit that used to be shared with us. UPS workers just negotiated $170,000 TC. I think that's enough to live a nice life, especially if two people are contributing to a household.

Productivity has increased by a lot. It's up to voters and workers to get their fair share of those gains. The uber wealthy are not going to willingly give it up.
