Originally invented as The Landlord Game , to expose the parasitic role of landlords, it was repackaged as Monopoly in the USA at the height of the great depression, as a sop to be sold to those workers who were being laid off and losing their livelihoods, a distraction from the reality of capitalist poverty. As capitalism is a social relation between classes its continuation requires the participation of both exploiters and exploited. By continuing the repetitive cycle of work and consumption we reproduce this alien mode of production. We are therefore our own jailers. However, since capitalism is opposed to human needs and desires, there is a constant struggle between those of us who produce and the bosses who reap the rewards.
Capitalism is a global system, with the rule of the market imposed everywhere, usually by force.
Hence the destruction of indigenous cultures. Indeed, capitalism's twin is war. Barely a day passes without the death of humans at the hands of capitalist weapons. To give but one example, British and US forces carry out daily bombings of Iraq, whilst sanctions have killed more people than the despotic Iraqi state. Mayday is the day above all others when we celebrate struggles against class society and demonstrate our internationalism.
