Immigrants coming into countries start companies at a disproportionate rate compared to natives.
Other than unquantifiable statements about what "Canadians want" everything you mentioned so far to justify this idea of "canada doesnt care if tech graduates leave" is falsifiable by data.
You're welcome to present data falsifying the actual claim if you think you have it (instead of the "Canada doesn't care" straw man or misunderstanding that you repeat above, noting that so far you have not even refuted your own straw man by presenting any data).
This is your claim that I engaged with. If your claim is true it literally means that Canadians do not care if those people leave, in fact they would prefer it. My argument is that you're wrong and Canada and it's people would rather have more tech workers and more tech companies.
I don't believe I'm misunderstanding so I think we should probably both give up at this point.
But I agree that we should probably disengage, so (barring exceptional new insights on my end) will leave this as my last post in the thread. Thanks for the chat.
There is a reason why there are not many startups in Europe - if you can have a decent life, secure job and a nice social security - no worth playing risky games. I would not be surprised if just sheer layoffs in USA led to more startups than in the whole Europe.
