Canada

Sorry it took some time for me to reply to your comment.

The TFW program was initially meant to bring in hard to find specialists to help local enterprises. This system was corrupted under Harper to exploit unskilled foreign workers for jobs in Tim Horton's and other low-wage positions. Companies couldn't hire anybody anymore with their shitty low wages so they found a workaround to keep wages cheap.

Later, as boomers started to retire, they increased the amount of immigrant workers that could enter the country to fill the missing positions. But they literally flooded the market with these workers to keep wages low. There were so many in fact that there wasn't enough positions for all of them. Many ended up doing Skip and Uber deliveries instead, living 5 people in a 1 bedroom apartment to make ends meet. This completely cut off any chances for local talent to access these new positions or even access entry level positions. That's why we still have entry level software engineer positions at 50-60k/year here in Montreal for example. (I was paid that when I graduated in 2008 btw, so adjusted for inflation, they are paid a LOT less than they should during a time where living expenses have never been so high.)

This caused all kinds of pressures in Canada. On the job market, on rental housing, financial support programs, food banks, etc. Canadian citizens in need suddenly had all these other people to line up with for all these things and that's unfair.

Sure we need immigration to cover lack of workers. But the rate at which they were let in was way too high.
