The 90s, especially the mid to late 90s, in America it was absolutely acknowledged that things were relatively good economically. As always there were impoverished people, ups and downs in the stock market, and a few scares from international markets that the media would play up for ratings, but overall things were good and the average American knew it and had plenty of opportunities to better themselves and their financial situation.
However the people in the 90s who said "we're doing great" without being diligent and knowing that any economic boom is always followed by an economic downturn are the people who have since lost a large portion of their wealth since 2008, while the insiders and the people who know how the system works, and know how to make it work for them, have only made more money in that time.
EDIT: While the media overhypes shyt, it is absolutely true that America's economic situation is far worse off now than it's been at just about any point since we've become a true world power, though it is still better off than just about every other country in the world. Many signs point to it being unavoidable, and in turn a controlled collapse by design, in a move toward a more balanced global economy.
