Karl Marx for C21st

"...as that brainy beardy Karl Marx said, no person can ever build up a fortune just by his own labour, but in order to become VIP elite rich you must appropriate the labour of others. In pursuit of this dream, many ingenious human solutions have been applied throughout the millennia from slavery, forced labour, transportation, indentured labour, debt bondage, and penal colonies, right through to casualisation, zero-hours contract, flexible working, no-strike clause, compulsory overtime, compulsory self employment, agency working, sub-contracting, illegal immigration, outsourcing and many other maximum flexibility organisational devices." - page 222, Marina Lewycka, Two Caravans (2007, Penguin Books London).
