Wealth inequality is really an instance of homophily. Money attracts money. The rich get richer.
Wealth inequality harms the economy, because as people get poorer they can no longer participate in economic activity. Businesses need consumers with money to spend.
When enough people become sufficiently poor, uneducated, and angry, then you get Trump.
Juno - a ride-sharing service similar to Uber, but that differs from Uber in that it sets aside 50% of the share of capital to be earned by drivers as they give more rides (unlike the more lopsided distribution of Uber that heavily favours capital).
I will definitely give Juno a try if I'm ever in NYC, the only city it's currently offered. Thank you for sharing.
