Across the country, cities have been increasing the minimum wage toward levels full-time workers can actually live on. But St. Louis is going the other way. On Monday its minimum wage will drop from $10 to $7.70, reversing a city-mandated increase that happened just three months ago. The rare rollback wasn’t the city’s choice—it was forced by the Republican-led state Legislature, which passed a bill prohibiting city-specific minimum wage increases.
