The Republicans proposed bill is actually not a healthcare bill;  it is an insurance bill.  It is designed so that the insurance companies can  be highly profitable again and the CEO's get their big salaries back.  People will be back to fighting with their insurance companies for coverage denied when they come down with an ailment.  Back to junk insurance we go.  Maybe more free clinics will pop up around the country.  I volunteer at one.  Many of the clients got insurance under Obamacare, but couldn't find a physician to take care of them.  I asked our director if it was some kind of county conspiracy.  She said the docs hate Obamacare because it didn't pay them enough.   I don't know if that was inherent in the policies or the insurers' fault.   
It took billions of dollars to set-up the infrastructure for Obamacare.  Surely, the stakeholders could figure out how to make this better rather than taking a machete to it and ending up with something worse.
