This is quite an incomplete analysis.
First off, neither Democrats nor Republicans are interested in supporting immigration into America. The last major immigration tightening was Clinton with the IIRAIRA and the last amnesty was under Reagan. Since then, neither side has been interested in bringing more legal immigrants to the US. After all, the Biden administration is about to allow 100,000 green cards to expire unprocessed and disappear into the aether. At least Donny was honest about it.

I also live in America, and I am not saying anyone's overpaying trash collectors.
> That way, Canada can get their trash collections, and we in America can get their engineers.
And yet this is only part of the story.
> That way we can poach your high value citizens who are overtaxed.
The lowest tax rate in the US/CA is Alberta and the highest is Quebec. The rest of the US and Canada exist in between these two Canadian provinces. If you factor in health care, basically all of Canada costs less to live in than America for the average individual. YMMV of course.
However, saying Canadians on the whole are "overtaxed" is an indication you haven't given an honest look at what the rest of the western world looks like outside of the US.
As I've been saying, that's only part of the equation. Folks don't move to the US to evade taxes lol - Silicon Valley is among the highest taxed places on earth but still attracts the world's best talent. It's not about the taxes - it never has been. Some small tax break isn't going to get me to leave the Bay Area. I'm confident my opportunity here will outperform the delta. Until that opportunity no longer exists, then I will leave without looking back.
