I will admit with subsidies is it possible that there are now fewer people who do not have access to health insurance (health CARE being another issue entirely) however everyone I know who was already paying for health insurance has seen costs increase since obamacare. I say that Obamacare has created a good deal more “struggle” for everyone I know.
I can see why AARP backed it. If you are in the premium subsidy range, the subsidies are bigger the older you become. Someone in their 60's can pay next to nothing in premiums if they can manage their cash flow. A couple aged 60 or so outside of subsidy range might have pay $15K a year in premiums for a silver plan. That same couple can get a silver plan for under $6K a year if they get their income to just below 400% FPL.
