[quote=jpinpb]The only job that will be secure are those that demand be physically done here. [/quote]

Although that is true, but eventually when all other jobs are gone, the salary of these “secured” jobs can command will also drop. But there is nothing unfair about it. A good job is not an unalienable right of US born citizen. If someone can do the same job at a lower salary, the opportunity should be given to them. If a country manipulates the currency so that the salary is low, it will without a doubt face trade surplus and have to use their excessive trading surplus to lower the cost of the money of the country that has the biggest trading deficit. So people in those country can afford to buy things at lower salary.
That’s the cycle of globalization. It improves the living standard of the average people… unless, of course you are the unfortunate soul that are out of job because of your skills are insufficient to compete in the global job market. Otherwise, if you really want a job, you can at least migrate to the currency-manipulated country, and have a very decent life there.
