Skyrocketing inflation is hurting those who can least afford it: single mothers, retirees, those on the fringes of the labor market, and people working for fixed hourly wages.

A new analysis this week from the Committee to Unleash Prosperity estimated that average earners are losing the equivalent of about $50 a week as inflation significantly outpaces wage growth. That’s a tank of gas, a grocery shop, or a utility bill. President Joe Biden’s chief of staff Ron Klain couldn’t have been more wrong when he said last week that inflation is a “high class” problem.
