There will always be "labor somewhere else". Have we not learned anything with all the industry moving out of the US and other developed countries? Corporations ALWAYS find a way to get the job done cheaper. Better? not always, but cheaper? Sure if they try enough they will! At least an H1B worker will pay taxes in the US and contribute to the life of the community they settle in, where some off shore contracting would be likely a net loss for the US.
