British and American studies opgave

I henhold til mit fag "BAS" er jeg stillet til opgave at skrive og "discuss" et essay om følgende udsagn mht til USA 

”As Thomas Pikkety has shown, in the absence of countervailing pressures, capitalism naturally gravitates towards increasing inequality. In the period between 1945 and the late 1970s, Cold War competition was arguably the biggest such constraint. Since the collapse of the Soviet Union, there have been none. As the popular backlash grows increasingly irresistible, however, such a winner-takes-all-regime becomes politically unsustainable”

Er der nogen der kan hjælpe med evt begreber eller emner/argumenter jeg komme med mht til overstående. 

På forhånd tak.
