I have insurance because of it and I am immensely grateful.
I think most people in this forum, unless they got covered by the Medicaid expansion or through their parents, lost out because of the ACA. I will actually have to pay more than double the amount I pay for insurance next year because of the ACA.
As a self-employed freelancer, I too have insurance solely because of the ACA. Best of all, it's at a significantly lower rate than when I had to make COBRA payments several years ago.
I bought insurance from the individual market last December and it was much cheaper than I thought it would be. Of course, it doesn't cover pre-existing conditions or maternity coverage, but it covers everything else after a $2,500 deductible. The plan is grandfathered in till this December but after that I must buy from the exchange. Those plans have premiums that are double what I am paying currently, and a higher deductible. My experience with the individual market was surprisingly pleasant and I would like the option of not having to pay for maternity coverage, which is not an option on the exchange plans.
