Bernie Sanders has shown that socialism is no longer the barrier that it used to be during the Cold War.

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

The workers should take over the factories, and shut down Boeing's profit-making machine.

Capitalism is based on ruthless exploitation and competition, and leads inevitably to the development of mega monopolies.

There is plenty of work to do, but big business isn't investing in rebuilding a green economy for the 21st century. Instead, they put their money into a gigantic financial casino, and when that led to catastrophe in 2008-9, they made us pay for it.

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.

On the basis of capitalism, victories like raising the minimum wage are only temporary.
