Billions of people benefited from safe and efficient lighting. Billions more were the ultimate beneficiaries of the computer, and untold billions benefited from healthier lives gained from access to tetracycline.
President Barack Obama, in stoking up class warfare, said, "I do think at a certain point you've made enough money." This is lunacy.
