Increased inequality and decreasing mobility pose a fundamental threat to the American Dream, he said.

For all the new attention devoted to the 1 percent, a new dataset from the Equality of Opportunity Project at Harvard and Berkeley suggests that, if we care about upward mobility overall, we're vastly exaggerating the dangers of the rich-poor gap.

Based on my analyses of the data, of the factors that Chetty has highlighted, the following three seem to be most predictive of upward mobility in a given community:1.
