Of course not, but you seem to miss the point: no company is going to pay $500,000/year for a part-time office assistant, $200,000/year for a bus boy, $2 million/year for a construction worker, $100,000/year for a farm laborer.
There is no developed country on earth where labor shortages are addressed by "just increase the salary until you find a native-born person to take the job."
