Are think tanks necessary for greed?! NO, they are not. Greed is a basic human trait. Reining in greed requires scholarship, thinking, and imagination. The billionaires have started “think tanks” to make selfishness and greed seem palatable. They promote greed under the guise of freedom. These “think tanks” do not look for both/and solutions. The billionaires have the what’s mine is mine, and what’s yours is mine also mentality. No sharing in their world.
