Socialism is a fundamentally different social system where the world's resources are not controlled by a greedy, undemocratic oligarchy. This is not the same as the capitalist welfare states that have existed in some European countries.

The underlying issue is the system of capitalism itself, and under this system the best means for regulating or checking their power is not relying on a government which represents the interests of the rich but for millions of working people to become politically active in workplaces and communities through building unions and our own political party.

We have a rotting infrastructure that is literally poisoning children in Flint, Newark and elsewhere.

Whether or not you agree with Bernie Sanders' version of socialism, it is enormously significant that, for the first time in US history, a presidential candidates who calls himself a socialist has had an actual shot at winning the presidential election. And to his credit, he has not backed down from the label.

We've seen the weakest economic recovery since World War II, and massive levels of inequality and debt.

Socialism is a society where the resources are used democratically to provide a better life for all, based on ending the dictatorship of big business over the economy and politics.

While we still live in a capitalist society, we of course will fight for whatever reforms help make life better for working people.
