Of the many unacceptable costs of living with capitalism, probably the biggest is its periodic tendency to generate orgies of mutual slaughter that originate in the same way. Contradictions and economic conflicts between capitalist blocs become increasingly antagonistic then eventually erupt into global wars.
The surge in capitalist markets from 1997 to 2007 was only achieved by deliberate, reckless stimulation of credit growth, enacted through a combination of abnormally low interest rates (relative to inflation) and exceedingly lax regulation of both credit and housing markets.
Anxious to work out why the oldest working class, the British, had avoided moving to revolution, external commentators at the height of empire concocted a false argument in an effort to explain away this behaviour. In some circles it is still lazily dispensed a century or so later.
