>I know this is being overly reductive, but I think it sort of boils down to not enough minimum wage workers that vote and everyone else either not caring about low-wage workers, being held hostage by "right to work" (means you can get fired any time for any reason) laws, or relying on job hopping for wage increase.

Are you talking about low wage workers, or minimum wage workers? The minimum wage is so low that only 1-2% of workers earn minimum wage.
