The connection is that the ACA rates, and rate-increases are out-of-touch with the employer-offered system, even when those firms are tiny and not nearing some kind of "scale" cost-savings.
I have been hollering about this issue for years, and I've yet to have someone say "Ya know, I actually experienced something radically different." So where is all this evidence you claim but can't be bothered to provide?
There also isn't one "employer offered" system. In addition to the aformentioned small-group marketplace, there are also large group plans that cover big companies, and very big companies often self-insure, using health insurance companies solely to administer benefits but financing the care themselves. Can you be specific about which of these kinds of health care financing have been impacted by the ACA, and how?
The only connection you’re making here is that your own costs went up after the ACA. It’s a post hoc fallacy.
