You’re right - it’s a big racket. All this publicity about Obamacare making health coverage more available. It just seems to benefit the insurance companies.
You pay a high premium per month, then pay a deductible, then usually coinsurance. If you can go with all copays that’s desireable. But many plans use coinsurance, which if you have a surgery you will really pay a lot of your savings.
It’s a scam.
