I can do nothing about the way you think, but dumping does work, if it is targeted towards a market that one can capiture (drive competitors out) and then be milked of a profit. Numerious examples abound, John D being the most famious, Japan used the tactic with success in taking over the consummer electronics industry in the usa. Profits at home subsidizes market take over abroad, tried and almost repeated with auto's in the 80's, China is doing the same today.
In order to make a compelling case along these lines you've got to provide some documented evidence that Japanese companies were selling electronics and/or autos in the U.S. for less than it cost to produce. Autos are a terrible example in any case, since this was one industry where the Japanese had no need to "dump" product in the U.S. market. By the mid 1980s many U.S. consumers were willing to pay more for a Japanese car than for an American one -- simply because by that time the quality of the Japanese car was far superior.
