Lower access to transportation for poorer Americans creates a kind of negative economic feedback loop. People need access to high-quality transportation in order to find and retain better jobs. Indeed, several studies have shown that transit access is one the most critical factors in determining upward mobility. Poor Americans are likely to have lower-than-average access to transit, but often are unable to move out of poverty because of this lack of transit. Investing in infrastructure thus is a way of increasing social and economic equality.
