Bernie Sanders says that the biggest banks that dominate the economy should be broken up into smaller banks. This would be far more radical than Hillary Clinton's proposals to regulate Wall Street.

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.

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

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.

What Bernie Sanders is calling for is incredibly important. Things like a $15/hour minimum wage, single-payer healthcare, taxing the rich, and free education. The radical reforms he has popularized are a key part of any socialist program today.
