The Beatniks were a fringe group, hardly representative of the culture of the mainstream. They did pioneer irresponsible, anti-social behavior, but the true masters were the boomers. The policies of the great society were intended to address perceived and actual inequities of institutionalized racism and poverty. The disastrous effects of those policies were not apparent until much later.
The Beatniks were sort of like the first obscure rappers and hip hop performers.
