The GAO has been questioning the “high tech labor shortage” as far back as 1999.
This kind of shortage shouting propaganda has been going on for 25+ years since H-1B law requires a shortage in order for more workers to be imported.
There is, in fact, a surplus, not a shortage.
Most shortage shouting is hype and PR.
There is no shortage, never was, never will be.
Foreign countries want our jobs. It’s that simple.
