You're claiming the native population of rich western countries are uneducated? And immigrants from the third world are all doctors and rocket scientists coming to save the day? uhuh...
Have you spent a day in Australia? Overflowing with homegrown bogans working in resource extraction and the trades (at best), meanwhile professionals like Drs and Scientists (including Computer Scientists) are overwhelmingly migrants. So yes, that's exactly what I'm saying.
Those working in resource extractions and the trades are some of the most objectively productive sectors of the population, even more so than computer scientists.
It has definitely been noticed how immigrants don’t tend to work in the trades. It is one of the key issues reducing support for immigration due to a shortage of tradesmen and housing only becoming more extreme when you take in doctors and computer scientists instead of carpenters and plumbers. If these governments took in more people who actually were skilled tradespeople, there likely would be more support for immigration, but I honestly think the people who set immigration policy are mostly white collar types who do not respect tradespeople or understand the desperate need for them and just see them as uneducated bogans to turn your nose up at. It’s incredible to me how you observed one of she biggest problems with contemporary immigration but completely misinterpreted the situation instead of thinking “hmm, why are all these Australians working in a different line of work than me, maybe they know something I don’t!”
Canada only instituted a category based immigration system specifically to take in more tradesmen to START to remediate this problem in May 2023. If we were taking in way more tradesmen a long time ago, contemporary political issues wouldn’t even be issues because as we took more people in they would have been building enough houses for their countrymen to keep cost of living under control.
The people here "concerned" about immigration are starting a conversation about how points based, highly selective visas for educated, experienced professionals, coming to work in fields the homegrown population don’t, need to be made a lot stricter... using chaos with student visas as the justification. Just what?
The problems with the economy you're mentioning are because of the exact reasons I mentioned - Australia and Canada are simple aren't competitive, dynamic economies, they're essentially glorified banana republics trying to pretend you can have a healthy economy based on resource extraction, fixing up each others houses for tax breaks, with a sprinkling of property developers building condos for foreign investors on top.
"resource extractions and the trades are some of the most objectively productive sectors of the population" "why are all these Australians working in a different line of work than me, maybe they know something I don’t" <-- this is comical, and so is attributing policies failing to immigration and immigrants.
In any case, people who think like you are in control so congrats and good luck with it.
