My limited economics knowledge suggests that buying inferior products does not spur innovation. Refusing to buy them does. Folks tend to follow rewards. Reward poor performance and you can be sure to get more of the same. Detroit stepped up when they lost sales to Japan. BTW - My JD 1070 has a Yanmar engine and the tractor was made in Japan. The dealer bragged the tractor was engineered by Deere, so I told him I would gamble on that and buy it anyway:)
