With California and New York both exploring statewide single payer healthcare it looks like the Overton window is moving closer to legitimate discussion of a nationwide single payer plan in the US. It’ll be interesting to watch, since this is such a hot-button topic here on many levels.
Something is going to have to change. As it stands, there isn't a plan on the national insurance exchange that I can buy that's even remotely as cheap as my company's plan (actual premium, not just the fraction paid for by employee).
Insurance on average is always more expensive than not having insurance on average. The question is given that risk, how much of a premium can / will insurance companies take. Turns out they like high profits and low risk.
