Big Oil, Wall Street and big business as a whole - they stand in the way of the kinds of change needed. They are fiercely against the radical reforms Bernie Sanders is popularizing.

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.

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.

This is what happens under capitalism - as long as corporations and the super rich own the economy and the politicians, every new generation has to fight hard just to defend itself.

Bernie Sanders talks about socialism in Scandinavia, and he's correct to point to the huge victories the working class has won there through struggle, such as socialized medicine, free college education, and paid family leave. But if you talk to working people in Sweden or Norway today, you will find out that many of those past gains have been eroded and some virtually eliminated, including massive under-funding of healthcare and other public services and a return to for-profit systems that are unaffordable to working class people.

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.

When the New Deal programs were passed in the mid 1930s, millions of workers were joining unions, striking, and occupying factories to fight for a better life. It was this radical labor movement that forced the establishment to make concessions.
