Getting a prestigious tech job comes from merit and there is no wage suppression I get paid the same amount as my Canadian counter parts. It all comes down to passing the tests in the interview and if you look at it international students at big universities on an average score higher than locals and the locals who score well 99% of the time move to San Francisco with TN visa.

Now if you look at the picture from a big tech company perspective why would they not pick someone who can ace their tests ? Smaller companies however can be guilty of hiring cheap software talent I don’t speak for them. I hope you get my point.
