That could be a step in the right direction as one of the complaints against the ACA is that employees are having to shoulder a bigger load of their health care costs than they were previously. However, the increased deductibles and out of care costs are just as much of a problem as the increased premiums. (https://www.washingtonpost.com/news/wonk/wp/2016/1...
One of the reasons the ACA has been unsuccessful is because it's cheaper for many healthy people to pay the fees imposed on those who don't have insurance than it is to pay the high premium costs. This means that those who have chronic illnesses are a greater percentage of insured Americans which is pushing premium costs higher and higher.
Another interesting fact is that there are millions of Americans who don't have insurance who would qualify for federal subsidies if they applied. I don't know if that's because even the subsidized premiums are too expensive, because the online system can be complicated to fill out, because people don't know they may qualify, laziness, or a combination of the above.
I don't think that health insurance reform is the only thing we need to do to fix health care costs in our country. We need to focus on preventative medicine and healthy living as well. The problem is, it's easy to point fingers at health related problems (insurance related or not), but it's harder to write effective legislation.
