Why Millennial Nostalgia is Actually Good

I think Millennial nostalgia, or 1990s nostalgia in general, is actually a good thing, because it reminds us that society can be better, and that it doesn't have to be the way it is now. Our task, I believe, is to move beyond simply wallowing in nostalgia, and actually doing something useful about our current situation. What conditions made the 90s great, that we don't have anymore now? Or conversely, what conditions are making our society horrible right now, that we didn't have back in the 90s? These questions often inform my own politics, and my views on various social issues.
