"The system [capitalism] produced an ever-expanding flow of goods and services, which the impoverished proletarianised population could not afford to buy. Some 20 years ago...this would have seemed outmoded. But it needs another look, following the increase in concentration of wealth and income." These are not the words of a socialist but Samuel Brittan, the Thatcherite columnist for the Financial Times, giving his summary of Karl Marx's analysis.
In the 19th century Marx explained that capitalismcreated a trend, with brief interludes of growing prosperity, towards the concentration of wealth and power in an ever decreasing number of hands at the top of society, with increased poverty and misery at the bottom. This has never been truer than today.
