The main reason that more uninsured haven’t signed up so far is it still seems too expensive, even under the Affordable Care Act. From Kaiser Family Foundation:

Cost Is Primary Reason For Remaining Uninsured

This reminds me of candidate Obama’s main complaint against the idea of the individual mandate, which if mandates alone worked we could end homelessness by just mandating everyone buy a house. The problem is cost, not a lack of desire.

Health insurance is very expensive. Even with the subsidies in the Affordable Care Act buying and/or actually using the required coverage can still be a financial burden for many.

This cost issue can be addressed by throwing even more subsidies at the problem or ending the significant overcharging of Americans for all health care services compared with the rest of the first world. Of course, Democrats wanted to both cut deals with the industry and get a low CBO score, so we were left with an Affordable Care Act which is short on the “affordable” part for many.

Sadly, instead of focusing on addressing this cost issue, a group of Senate Democrats plan to “fix” the law by creating the illusion of affordability with new “Copper plans.” These would be extremely high deductible policies which would have lower premiums because they would not actually protect people from unforeseen medical expenses.
