Maybe Britain is in decline. Pretty much every bad thing you can think of, which I can agree is bad, is way down compared to 1960 in the US.
I think you're dramatically underestimating how modern 1962 was. The only difference was that sexism and racism were the overt norm and people actually smoked and drank more than they do now, and they were passing doobies and shooting the bull, and shtupped other guys' wives.
Leave the 1950-60's romanticism for an alcoholic, stogie champing, preppy, misogynistic, racist, son of a like me. From the Kerouac Beatniks to the Wallstreet Preps I'd be getting my rocks off in a tall glass of scotch. I'm old fashioned. I just want to jitterbug with hot chicks if you know what I'm saying.
