Pass a minimum wage increase. I'm already on record pushing for that.
What you want is a total decrease in health care costs. Single payer wipes out the insurance companies, which is a start. IPAB has a shot at reducing costs, which goes further. But you want affordable healthcare for everybody. The only way to guarantee that is a National Health Service like the UK or something similar to Canada's system. You ok with taxes going up to pay for that? On who should the tax increase fall?
