At this current point in time, you are both correct. It's gotten to the point where I'm genuinely starting to wonder if this state might be permanent, even though it's theoretically "impossible" because there will "always" be a reversion to the mean.
Yeah. It's gone on long enough that I'm wondering the exact same thing. Of course, if it doesn't, that return to mean is going to be a real bitch to ride out.
Printing money can achieve both of those, but it isn't necessarily sustainable. When I was younger, I would have said it isn't sustainable, but now I'm not so sure.
