“In the 21^st century, globalisation has fallen away and regionalisation is emerging.  Inequality of wealth and income in the US and the G7 is at extremes.  But above all, the profitability of capital in the imperialist bloc is near all-time lows.  The collapse of the Roman Empire also ended the dominance of the slave-owning mode of production, to be eventually replaced by a feudal system.  The increased internal disintegration of the US economy could not only end its global hegemony, but also usher in a new mode of production.”
