Silly statement. You can say that about other commodities and services. What responsibility does a government have to its people? Should we allow the unlimited importation of cheap foreign labor to enable our businesses to compete in the global market? What happens to the native born? Is the idea to drive down wages to third world levels?
There are many examples of developed countries competing successfully in global markets whether it is cars, energy. or agriculture.
We are artificially creating a local market with lower costs and prices by importing cheap foreign labor. It has social, cultural, electoral, demographic, and economic consequences.
Those global companies that are successful tend to have, say, manufacturing in Brazil, customer service in India, etc.
And, yes, commodities work in global markets as well, except they tend to have higher shipment costs than the more intellectual product of highly skilled employees. We can not allow in more highly-skilled competition, but that means that companies based in less expensive markets will accelerate their gains on competitors in the US. (E.g., Indian and other Asian tech companies.)
Do you think the Apples of the US manufacture their products in the US? Not bringing in more high-skill labor simply means that type of company will offshore more of their engineering and other high-skill labor.
