Yeah, I don't think any healthcare system is going to be a silver bullet so long as supply is ultimately a bottleneck. Which is a bit broader in scope, being impacted by macroeconomic factors, the educational system, regulatory requirements, technology, and so on.
We should take steps to optimize both supply and demand, but I don't think it'd be accurate to characterize the situation as "single-payer = long waits and multi-payer = short waits". More like higher demand with all else being equal means relatively longer waits, and all else being equal single-payer increases effective demand. But improved health, improved safety, and lower population are all things that drive down demand, all else being equal, so obviously there are a lot of factors here.
Despite not being single-payer, and despite its suppression of effective demand (with high latent demand among those priced out of the market), I'd argue that the current US system is far from optimal at maximizing supply of actual care relative to its full potential.
