Spin that Mr. Knownothing.
They no doubt were forced to in order to avoid raising the wage even more to attract US citizens.
If they really and truly wished to hire legal workers, they would raise wages and recruit more aggressivley. If a job is truly so distasteful and difficult that 'no American will do' it, then by the laws of supply and demand, it should pay more than less strenuous or offensive jobs.
Mass importation of labor (legal or otherwise) is a transparent ploy to artificially depress wages in certain sectors. It's class warfare.
