NEW YORK (May 15): THE Wall Street Journal notes in an editorial that, according to the Industrial Bank of Japan, it will soon be costlier to produce radio and television sets in Japan than in the U.S. 'Whereas in 1970, the comparative unit cost was about 20 per cent higher in the U.S., in 1975 it is expected to be 20 per cent higher in Japan,' the newspaper says. 'What a difference time can make,' the Journal says. 'Only a short while ago many Americans were complaining about Japanese radios and TVs flooding U.S. markets. Labour unions demanded protection from goods allegedly produced in Asian sweatshops. Congressmen warned of dangers of growing foreign investment in the America. 'Some U.S. politicians seemed to view Japan's U.S.$4,100 million trade surplus as a personal affront. And a few months ago a senior State Department official cautioned Japan against mounting an export drive to offset the higher cost of oil exports. 'Clearly, Japanese 'sweatshops' exist only in the imagination of protectionists. Either that or workers in much of the world would gladly settle for similar 'exploitation'. At the beginning of this year Japanese wages averaged $435 per month, in direct and indirect benefits. This is higher than the wages in such industrialised countries as Britain, France and Italy,' the paper says.
