Economist are the magicians who ask you to focus on their one hand while their other hand does the trick.
Now imagine a scenario. All the US software jobs are still in the US. Kingfisher airlines will still need the jets so they will go ahead and buy $$ from the market and buy the jets.
India does not get the free jobs from US so they become more innovative and competitive in many other areas as also in Software. The country grows in a real free market scenario.
While if TCS and Wipro get the $$ then they will make 5 lacs out of an employee per month pay the employee 30K to 40K a month and pocket the remaining amount.
You can repeat as much as you like there is a clear evidence everywhere as to how many people lost jobs and are still losing. How many people have to settle for lower jobs and lower standard of living just because their jobs have gone to India.
