In my own book, I treat the 1848 revolutions as one pivot, from which point the bourgeoisie became more conservative for fear of 'proletarianised democracy' (as I blogged a few days ago, the liberal historian Bennedetto Croce dated this development from the 1830s). At the other end, I see the international 1968 as another pivot, after which the politics of the bourgeoisie become ever bolder and 'revolutionary'. The 1970s was the decade in which this came evident. The rise of this audacious 'New Right' was driven at first by the 'small battalions', those outside the corporatist golden triangle of state/capitalist corporations/labour unions.
Sandbrook's excellent book on the United States in the 1970s, Mad as Hell: The Crisis of the 1970s and the Rise of the Populist Right (2011) chronicles and analyses this period with compelling drive. As he says, both the New-Left and Rightist libertarianism oweded something to the 1968 rebellion against the 'welfare-warfare state'. As Sandbrook wittily puts it:
Weedy pacfists who marched against "the machine" might sem a long way from Ayn Rand's muscular mavericks, but their disdain for authority meant that they were, if not bed-fellows, then at least propping up the same bar. [Mad as Hell, p. 278].
The 1970s saw a ground-swell against taxation in the US, partly because inflation was bringing middle incomes into the upper tax bracket, partly because of expanding welfare programmes.
Sandbrook quotes a Brooklyn housewife:
"My husband works hard and the taxes keep going up. The taxes go to the poor, not to us. And the rich have their tax accountants. The middle-income people are carrying the cost of liberal social programmes on their backs." 
'Proposition 13', a Californian referendum to mandate property tax limitation in 1978, was actually opposed by big business, as they feared that taxes would be shifted from household property to corporations. Prop 13, nonetheless, passed overwhelmingly. Over the the next ten years, $228 billion was 'saved' in taxes. Says Sandbrook, "the biggest winners were the major corporations that owned most of the property in the state." [284-5] So, this rise of the New Right obviously benefitted the capitalist leviathans, but there's no doubting its populist roots.
I mention Prop 13, and the tax revolt, in my book. But for a fuller flavour of this and much more, check out Sandbrook. He makes a rivetting read. Highly recommended.
