Nonsense. If our international competitors take a price increase, for any reason, we will, almost immediately, increase our prices. If Trump hits imported autos with a 45% tariff, it is lunacy to believe that domestic producers are not going to increase their prices.
BS, there is still domestic competition to stop that. One manufacturer reduces sticker price then the others follow. It is called supply and demand. Prices would stabilize as domestic manufactures regained market share. Eventually prices would be marginally higher form the slight increase in domestic labor costs. Now if the domestic manufactures "collude" to keep prices artificially high for any reason then that is crime under the anti trust act.
