So if I had one closing and modest suggestion, let's set a stable oil price in Europe and the United States. How do you do that? Well, let's put a tax on oil that is a non-revenue tax, and it basically says for the next 20 years, the price of oil will be -- whatever you want, 35 bucks, 40 bucks. If the OPEC price falls below that, we tax it. If the OPEC price goes above that, the tax goes away.
