You're a tad muddled. Obamacare is okay, but as Obama said, it vastly can be improved and would be. If you recall, Dems had to agree to all sorts of Republican demands to get it passed: the problems we now experience are a direct result (plus Trumps cutting payments and trying to cut all federal inclusion). Single-payer and public option were Dems' first choices, but Mc and Ryan said they were dead on arrival in committee. 
I'm sure you recall W's drug bill? Same problem: Repubs took away bargaining for cheaper prices Big Pharm. That's the sole reason Americans pay FAR more than any other citizens for drugs.
