I think Congress is scared to stop providing health insurance to those who do not pay for it. 

Honestly, limit Medicaid and any taxpayer subsidized health care plans to 6 months total, and allow people to reapply for six more months once every ten years. Cover just actual life or death emergencies in the ER's. Walk in with a runny nose, their bill, and it is pay up front. Limit all other care treatments to only medically necessary ones. 

Children are the victims in their parent-controlled homes. 
Always cover them, but only them.

Costs will go down.
