The Fight for 15 movement claimed its biggest victories to date last week, with both New York and California passing major minimum-wage increases.

California’s rate, currently one of the highest in the country at $10 dollars per hour, will rise incrementally and reach $15 dollars by 2022. In New York, the wage floor will go up according to business size and location: larger New York City employers (ten or more employees) must pay at least $15 by the end of 2018, while smaller employers in the city (fewer than ten employees) will have until the end of 2019 to meet that mark.

Westchester County and suburban Long Island wages will hit $15 by 2022. And upstate New York employers will have to pay employees at least $12.50 by the end of 2020, after which the state will determine how to get to $15.

It’s disappointing that the $15 requirement won’t cover all of New York state for some time, and that upstate New York workers won’t see a $15 minimum for several years at least. Unlike California, New York also still allows tipped workers to be paid a lower wage. But considering the trajectory of the US minimum wage over the past four decades, these are enormous wins. Simply put, the US has never seen an increase this large.
