60s didn't fail
I don't think that many in the hippie culture were really trying to create a political movement -- or had an agenda to change America.
There were exceptions, of course. The demonstrations at the 1968 Democratic Convention, for example -- but that was from activists in the parallel movement against the war in Vietnam.
I think the 60s -- or hippie culture, if you want to call it that -- have profoundly influenced the direction of the country, even without an agenda. Race relations, trust in the gov't, freedom issues changed considerable.We went from Pat Boone to Mick Jagger. All the normative cultural artifacts were radicalized. A lot of the seeds planted by the Beats came into flower.
