Don't let the facts get in your way, but Walmart pays well above minimum wage.

Raising the minimum wage will only make the problem worse. When the minimum wage goes up, there are less jobs. How far do you think McDonalds is from replacing their staff with robots? Another couple minimum wage hikes and many manual labor jobs will just disappear. Also, when minimum wage goes up, the costs for needed items rises as well quickly eating up any raises.
What you should really be advocating for a is a basic income.

Also, forget affordable healthcare, we need to just have single payer and get it over with. We pay so much more than all the other countries for health care, without any improvement of outcomes.
