I have not. It might be true. I'm currently paying a little over 10K annually right now for my not-cheapest family plan, and with the employer contribution it might well be close to 20K. Add in a little inflation, and it's over 20K even for the cheap plan.
However, since the ACA provides for discounts based on need, people do not get priced out of care.
Then it may have been useless propoganda since I cannot relocate that info. I will disregard it as such.
