You missed nothing (he answers sheepishly!!) I have made a mistake and I am embarassed. I apologize.
It was late. I used a barrel of crude at $100/brl, not gas at $4.00/gal! Huge difference and mistake. I might add, humbly, that the amount of workers required to make 1 million new domestically produced autos would make up the difference by huge amounts (@1-2 workers per vehicle)..... many billions in fact, but no one would hear that from me at moment. I am wrong in my math.
