Well he is doing something. Recently he moved to curb student intake. So that accusation is straight up false.
Rightie 'solutions' are motivated by racism and are impractical. They are designed to appeal to emotion, not reason. For example we recently saw a couple of threads on Canada turning Indian or speaking Punjabi. The guy who started the thread was not very smart. Usually a smarter rightie would sugar coated it by using the "housing crisis" or "the economy" etc. Not that they actually care. Which is also something we have seen many times here on this board.
Actual solutions, however, are usually compromises. You talk about after effects on people? Solutions to immigration should take effects on immigrants into consideration, not just Canadians. Infact, it should be the first priority to consider what those effects may be on immigrants as immigrants take huge risks to immigrate. Trudeau I believe does that. There is a move in the right direction to reunite families, parents and grandparents etc, while keeping those numbers reasonable. However, he got the student stuff wrong, and he has moved to correct it. He also got the temp worker permit thing wrong, but IRCC has currently adjusted issuing Permanent Residencies that heavily favour temp workers who already live and work here. Which is again the right move.
PP on the other hand, has nothing of substance to say. His typical "This prime minister...blah blah blah". It is basically an exercise in finger pointing. Nothing of actual substance. So let me know when he details what he is going to do and most importantly HOW he is going to do what he says he wants to do, and then we can may be talk.
