Well, no. First of all, it's not collapsing, nor is it going to ("No ‘Death Spiral’: Insurers May Soon Profit From Obamacare Plans, Analysis Finds"; "Health insurers start getting the hang of Obamacare as GOP pushes replacement plan"). The only way it could collapse at this point is if the current GOP administration deliberately moves to destroy it. Which is apparently on the table ("Trump Threatens to Withhold Payments to Insurers to Press Democrats on Health Bill"). If that happens, yes, I would agree that we'll probably move to some form of single-payer within 5-10 years. But if it was "designed" with the intent that Trump and the GOP would destroy it, then the Dems have really been playing some 11-dimensional chess. At the state-level the story is more varied, but in general states that have been implementing it well and as intended are doing fine and states that deliberately did the opposite are having a rockier time. Did the Dems trick Tennessee into deliberately undercutting their own individual market as part of some secret plan to force single-payer? If so, they're a lot savvier than I ever imagined. Somehow they knew all along that red states and the Congressional GOP would intentionally bungle things and force single-payer. Meanwhile, Massachusetts has been doing this for a decade and hasn't felt the need to pursue single-payer.
