The patients/consumers are the ones being screwed by Obamacare. They always have been. Hillary's single constant is crony capitalism. So long as the health care industry donates generously to the Clinton Foundation and the Democrats, they should do fine.
Actually I think the Aetna's of the world would love to see single payer. Somebody has to administer the claims. Private insurance companies now administer Medicare as fiscal intermediaries. The upside they get paid well to be paper pushers. They have no risk exposure if the government pays out more claims than revenue. A win-win scenario except for the revenue side which is us poor tax payers.
