The utter selfishness of the left. What does it say about someone who constantly demands that others pay the bills?

You missed the point.

Henry Ford, Fred Koch and the government — all without, perhaps, meaning to do so — helped each other. Henry Ford paid some of his own bills and, in doing so, helped Fred Koch to make money: certainly more than he would have made absent Henry Ford. Fred Koch did likewise and the government too… The net result being all three entities made so much more — created something in toto so much bigger — than they would have — could have — done all on their own. Taxes are the bills they should pay out of their success because without it, they wouldn’t have had nearly so much success. It’s all related.

The heirs and scions now pretend they did it all on their own when, in fact, there is no possible way they could have done so. They want to starve their own success by refusing to pay taxes that are part and parcel of this great web of inter-related and dependent economics.

What’s so difficult to understand about that?
