It's an era foreign to traditional liberal thinking

[OWS] "dominated by white sons and daughters of the middle class who began to decry police abuse and the lack of economic opportunities only after they and their families were affected. This distrust is not the fault of the movement, which has instituted measures within its decision-making process to make sure marginalized voices are heard before white males. It is the fault of a bankrupt liberal class that for decades has abandoned the core issue of economic justice for the poor and the working class and busied itself with the vain and self-referential pursuits of multiculturalism and identity politics." - Chris Hedges

For many in the present generation the situation is quite the reverse. They have fallen from grace, Many will never find work at a decent wage, Few will retain the family home through to retirement. It is difficult to abandon the old expectations and doubly hard to adjust to newly reduced circumstances,
The aims of the Civil Rights Era were initially legal with economic justice to come later. Intended to benefit the many, they fell to the manipulations of the few. The 1% unite to put down the 99% before they realize their superiority.
