Their dream is to get rid of highly trained American engineers and scientists who know their own value and expect a decent wage, replacing them with foreigners on H1B visas who are willing to work for fish heads and rice. (It's harder for someone on an H1B visa to quit and go work for another company if they get a better offer.)
Also remember, it's not the personnel department any more responsible for staffing, it's human resources . . . and one human resource is as good as another.
And of course, the consequences of their decisions will be delayed until after the exec retires with his golden parachute and guaranteed six-or-seven figure pension.
