Almost every country in the west is tightening it's system. In the UK claiming ILR will take a significantly longer period of lawful residence, and a shorter time will require you to meet a high income threshold. It is nearly impossible to get PR in Canada now unless you are fluent in both English and French and have a PhD or several years of canadian work experience. The bar has also gone up in Australia too.
The reason why this doesn't seem to move the needle on the anti-immigration vote is because the folks on that side can always just move the goalposts and be the "true" anti-immigrant party. I believe these days Reform UK wants cancel all ILRs and start actively deporting long term residents who don't meet an ever raising bar. Its madness.
