Because it caused costs to spike across the board for everyone else and 50k In nyc is nothing

Medical Insurance premium increases have been ridiculous for decades. It's been over nine years since I retired. Back when I was working insurance premiums were a major bargaining issue, right up there with wage increases. Long before I was on Medicare, the premiums for two party insurance was well over $1,000 a month. Amazing, since the school district that employed me was self-insured. The coverage matched one of the better Blue Cross plans. Obamacare did not cause health care premiums to go up, they'd already been going increasing each year.
If your interested in one comprehensive, 37 page study of U.S. healthcare cost increases, I suggest reading,
History of Health Spending in the
United States, 1960-2013 Aaron C. Catlin and Cathy A. Cowan, November 19, 2015. It offers quite a lot of information.
