Medical insurance is nearly as, or more, expensive as a lot of folks mortgages or rents for their family. Going to a single payer would be huge for raising a family.
Wages have to go up. Taxes need to not go up on working and middle class(which is what trump's existing cut is about to do). Regulation is needed on plenty of spaces like insurance, medical, etc.
Best move in the world would be if today's GOP actually embraced the majority of their base, removed the religion component of their message, and actually enacted policies to raise wages, and lower costs for workers.
