You're going to clean up that air that you're polluting. See the regulation? Like I'm changing the temperature on a dial. That's kind of a mixed system. And we have Social Security and food stamps, Medicare, Medicaid. We have lots of ways the government interferes with the economy in order to make sure that everybody's living at a basic level, that old people are not eating cat food and children aren't starving in the streets and that kind of stuff. Very few pure systems today.
