Inequality creates social degradation, social division, underachievement, criminality and great unhappiness. It is iniquitous and corrosive to the social fabric. So why do we have inequality? Some people would have us believe that the source of inequality is purely down to individuals. In our capitalist society this seems logical. Don't some 'work harder' and 'do better' than others? Don't some 'get on' while others don't? So it seems. But it's not like that. We live in a capitalist society. Our economic system is a great big engine which drives inequality. You can't have an equal society with capitalism, which is why inequality seems natural to us, because we have lived with it all our lives.
But there is nothing natural about this inequality - it is manufactured by capitalism. You cannot have capitalism and a socially just society. The two are mutually exclusive. Karl Marx explained to us how capitalism generates economic inequality through the mechanism of surplus value. This is an inevitable consequence of capitalism. It is what creates great inequalities in wealth between worker and capitalist. Over time it creates the society we live in now with a small number of super-rich and billions living in poverty and deprivation.
I've just been reading some of Tony Blair's book 'A Journey'. It's a fascinating read in a dark bizarrely comic way. Tony Blair built New Labour around 'getting on' and the chimera of meritocracy. But Blair, like all those who believe in the 'free' market, was, and still is, deluded. He tried to achieve social justice by employing the very market methods which work against it. He failed. The proof of the pudding is that after 13 years of these policies Britain is more unequal than it was before.
If you believe in a creating a socially just society you have to eliminate capitalism. You need to create an alternative economy based around public provision, mutualism and the private sector. Its important to understand that the private sector does not equal capitalism. Rupert Murdoch is a capitalist, your local hairdresser is not. There is plenty of room for local private and social enterprise in a socially just society. Just no room for capitalist corporations and their shareholders.
