China has nearly all of the manufacturing that we used to have. Somehow, we survived all that, as they are surviving. They apparently banned leaded gasoline after 2000, but there have been recent reports of it still being in use.
I’m still in agreement with Hamilton’s outlook on the USA “possess(ing) within itself all the essentials of national supply compris(ing) the means of subsistence, habitation, clothing and defense”, and I believe that pollution controls (on genuine pollution, not carbon dioxide gas) can be attended to by the private sector without the growth of overbearing executive departments that suck up treasury money to make business too expensive and too untenable to conduct within US borders.
