In San Francisco, the richest 5% of households rake in an average of $423,000 a year, while the poorest 20% make around $24,000. The income gap between rich and poor is even worse in Atlanta, where the wealthiest people make nearly 20 times more.
As the gap between rich and poor grows in the U.S., it's worst in big cities. In a Brookings Institution ranking of the most unequal cities in the country, Atlanta and San Francisco topped the list, but others were close behind.
