I disagree, our healthcare system was in need of reform and has not worked well for years. All due to prior government controls and interference. Mandated coverage, limiting who can sell within a state, the lack of tort reform and expanded government reporting requirements all drove up costs and lowered care over time. Otherwise, you're right.
Solutions to replace 0bamacare will be like putting toothpaste back in the tube. It's going to be difficult if not impossible. One item that will be required is to have an exit strategy for those people who did buy 0bamacare, getting them onto real insurance plans and off government care. One possible solution will be to block grant states who are saddled with Medicaid and let them handle it for the short run.
Now millions will be kicked off their plans they would have never been kicked off with uninsurability leaving one solution, bigger gummit.
