I 100% agree they could and should, but I don't think it should be made their responsibility. You also wouldn't have to tax very drastically, because replacing the healthcare system with something like Medicare for All would cost less than the overall cost of our current bloated system, so the money could just get reallocated and the tax increases would just shift the responsibility slightly to the wealthiest of us. It should be popular with the "party of small business" and "lowering tax for the middle class" since it would cost businesses and workers both less money for better outcomes, but they only pretend to have principles when it can be leveraged for power. Health insurance is a fucking scam, and the fact that we can't unanimously agree companies making money extorting us with our lives aren't beneficial to society is bleak.
