Washington, Feb 21: Chairman of the US Federal Reserve Alan Greenspan has strongly defended free trade in goods and services, now under attack by John Kerry and John Edwards, the two leading rivals for the Democratic Presidential nomination, as well as some Republican Party legislators. Addressing the Omaha Chamber of Commerce yesterday, Greenspan warned that protectionist cures that are being advanced to deal with the country's job insecurities would make the situation worse. He recalled earlier anxieties in the US to losing jobs to then low-wage Japan in the 50s and 60s, then to low wage Mexico and now to still lower wage China. The recent migration of service sector jobs such as employees working in telephone call centres in India, he said, is a new phenomenon, but whether in goods or services, the protectionist cures being advanced will fail to address the hardships and will only make matters worse rather than better. The answer to the anxieties about jobs going abroad is adequate educational training, he said. The high level of job insecurity at present in the US, with more than two million people in the workforce being unemployed for more than a year is not surprising, he said and predicted that the strengthening economy will lead to stronger employment growth in the US in the months ahead. But the main consolation he offered those worried about outsourcing is that "we have reason to be confident that new jobs will displace old ones, as they always have" though, he conceded, not within pain for those who lose jobs.
