As far as $1000 a month, I don't see health insurance cost that much. Closer to $500 a month really and that is for the Gold metal premium coverage. $1000 a month is higher than I've ever seen anywhere but I would assume if you're older and sicker your premiums may be higher as it makes sense.
So at $1000 a month you are looking at $12,000 a year. In general Obamacare offers subsidies but there are a lot of onerous requirements associated with those subsidies which make it less than attractive but if a person requires it to live then that is the best option.
