Inequality is the root of social evil 

…these things become the norm: that some homeless people die of cold on the streets is not news. In contrast, a ten point drop on the stock markets of some cities, is a tragedy. A person dying is not news, but if the stock markets drop ten points it is a tragedy! Thus people are disposed of, as if they were trash.

Trade Unions have been an essential force for social change, without which a semblance of decent and humane society is impossible under capitalism.
