Yes, that does not mean we shouldn't look back on the things in the past that were good & now are not. But if a wholesale reversion to a past time was possible, we would still find the golden parts of that earlier age to be apportioned to some, but not others.
Another consideration is that while I don't like life inside a panopticon, its absence in the 90's meant those of us fortunate to be "golden" simply had less awareness of those who weren't, hence the false impression that perhaps there was a lot more gold everywhere.
