They control virtually every aspect of our lives, our politics, our governments.
The rich and corporations can buy people and politicians, to ensure they receive favorable treatment and make more money. They create and fund groups to promote their agenda (less government, less regulation, reduced taxes).
They also work to ensure the masses are kept under control. One way of doing that is by organizing and funding “nonprofit” groups designed to stoke hate, anger, discontent, and protests. Focusing attention on rabble-rousers helps keep attention from being focused on the oligarchs.
