Th only cost factor that went down for most (initially) were the monthly premiums. But many of us said back then that the American people were about to learn the definitions for "deductible" and "out-of-pocket maximum". Sadly, too many are plainly stupid or indifferent to have cared.
I experienced no decrease in monthly premiums, at any time since 0bamacare. I did experience $6,600 deductible for just myself.
My monthly premiums almost doubled, while the deductible went through the roof.
