Obscene oil company profits?

The Democratic Party control of the United States Congress, the House of Representatives held hearings on the profits made by oil companies. These representatives of the people have forgotten that capitalism is or use to be the economic system in the United States of America. No profit is obscene as long as it is given to the stock holders as a return on their investments. These same Congressmen want the oil companies to invest about ten percent of their profits in renewable energy. Why? There is plenty of oil in America right under the feet of our citizens. Yet the Democrats and the environmentalist block any further drilling for oil in this country. All this while the spineless Republicans let these wackos allow America to be held hostage to despot regimes around the world that we import oil from.
