That's a bit of an oversimplification about Nixon (yeah, I'm going to be
that guy here).
While his policies on the surface were certainly within the framework of the postwar Keynesian consensus, they were also applied in such a way as to practically guarantee their ineffectiveness.
The Environmental Protection Agency, for instance, which Nixon so often gets credit for signing into law, was actually devised as a way to reign in the conservation bureaucracies scattered throughout the Department of the Interior and consolidate them under White House control.
Another example: Nixon appointed a CIA spook named
Frank Carlucci to head the Office of Economic Opportunity established by LBJ's Great Society. Carlucci was probably involved in the murder of Lamumba, and later became an acolyte of Donald Rumsfeld.
Then Nixon impounded funds approved by Congress, preventing their being spent on social programmes. The Supreme Court later
found this unconstitutional.
And, of course, Nixon vetoed the Clean Air Act, which was subsequently overridden.
Nixon governed "to the Left" of Obama superficially, but in a way oriented towards subversion of the Keynesian consensus. I have zero doubt Obama is more personally to the left, within a
bourgeois political framework, than Richard Nixon.
Don't let left-liberal revisionists trick you into believing in a bipartisan Keynesian Golden Age that can someday be restored if only you believe.
Too long, didn't read, not American version: if you're poor like me and you lived under Nixon, you might think you were experiencing a transitionary phase to socialism. In truth, the social safety net was being yanked out right from under your feet by the very man intended to administer it.
