Why were americans in the 1990s concerned about outsourcing?

Outsourcing is the practice of hiring people outside their immediate company to work on some portions of their tasks. This is to reduce their cost or expenses.

Americans are concerned about outsourcing by companies because they fear for their jobs and job opportunities. Outsourcing rates are cheaper than hiring office based workers and if the company really is focused on lowering their expenses, then, they would prefer to outsource their labor than in-sourcing it.
