Maybe the movement should stop pushing for a number and just say you want a regulator who just increases minimum wage by inflation every year, as well as setting absolute minimum federal minimum wage up to a level where you can actually live.
But without asking for legislation that gives a regulator the authority to set minimum wages, even if you get $25/hr, you’ll just have to get the movement going again ever few years.
This is not a novel idea by me, it’s done all over the world.
