There are certainly many problems with Obamacare such as the entire concept of the exchanges were doomed to failure before they began. Anyone with a brain knew young people were not going to join the exchanges to pay for the medical care of the older and sicker people.
The exchanges are almost completely filled with high medical cost people.
But the largest issue with Obamacare is the one size fits all base mandates for all policies, such as older people do not need coverage of adult children or birth control so why should they pay a higher rate for a policy that has a lot of extra stuff added to it they will never need?
A male gay couple will never need OB/GYN services either, or birth control, or breast cancer screenings, etc.
Lumping everyone into the same Government mandated coverage does not make any real sense.
