Not true. Homeownership is up since then, and far, far more Americans own stock and bonds today than when Nixon was in the White House.
Our standard of living has *increased* even though (actually, partially because of) our Dollar's decline.
Well since I was alive in 1970 (in USMC) and remember those days very well and I am still alive today, I can tell you with assurance that our standard of living is no better today then in 1971. Technology has given us new fun things like PCs and DVDs, but instead of one worker supporting a home (dad) it now often takes two (mom & dad). At best a wash.
