Unfortunately your numbers are way off. Prior to ACA my premiums for a Cadillac health plan were under $500 month for a large family. Within 18 months of ACA my premiums skyrocketed to $2,500 month. Eventually my plan disappeared. I couldn’t keep my doctors. Everything was lies. Now my premiums are still through the roof and my deductible is 5x what it was and my OOP max is 10x what it was and I still can’t keep my doctor. But hey, I have maternity coverage for my sons now. I have to drive into another county to find a doctor that accepts the current junk plans. Not alone, our community was hit hard by Ocare.
Unless the $500 per month for your "large family" was YOUR portion after your employer picked up most of the premium, that doesn't sound like anything I've ever seen anywhere in the last couple decades.
There hasn't been a low deductible, low co-pay, multi-family member policy with a reputable insurer that low priced in many, many years that I've seen. I have friends, former employers, family members, colleagues, business associates with a couple kids and they've all been paying over $1,000 per month for as long as they can remember. I remember an exhibit/tradeshow company I worked at between 1995-2000, 10 years before the ACA and our office manager spent the better part of a month EVERY year shopping for health insurance for us all and the amount taken from my check every week just for me was nearly $50 for a decent policy that didn't have high deductibles and co=pays.
The bigger point is that there are tens of millions of hard working Americans needlessly suffering and not having access to decent healthcare, let alone Cadillac healthcare because of its high cost. Combine that with the FACT that now nearly 50% of all workers earn less than $30k per year, Houston we have a problem. Vilifying other systems for valuing their citizens over the profit motive isn't going to make our system better.
