> experiment of mass migration has failed to work for the average person

Could you precisely articulate this experiment ? America has had stable mass immigration for the longest time, arguably its entire history. Do you mean the entire American experiment ?

In what manner has it failed to work for the average person and in what manner has it harmed their bottom line ?

> Overcrowded cities, erosion of quality of life, strained services

American Cities are some of the most underpopulated in the whole world. Its only crowded city (NYC) has high positive sentiment for immigrants and owes the core of its historic identity to mass immigration. Not sure how immigration erodes quality of life or strains services. The US doesn't offer much in the way of services to immigrants anyway.

> competition for housing

This is 100% a building problem. The US has had high levels of immigration for a long time [1]. Immigration isn't going to suddenly shock the housing system. While the absolute population of the US keeps increasing, American cities have stayed woe-fully underbuilt. [2] New housing also isn't being built where people could use it. IE. within commute distance from offices in city centers.

> suppression of wages

Unfortunately these have been a long time coming. The alternative is jobs being shipped out of the US. The issue is even worse in Europe, where education is worse, employees work fewer hours and skill levels in new-tech are limited.

Wage suppression occurs differently in low and high skilled jobs.

In the low skill domain, the US already overpays blue collar workers, unionized factory workers and restaurant wait staff compared to the rest of the world. These jobs aren't threatened by immigrants, they're threatened by automation.

Among high skill workers, it is a statistics problem. 7.5 billion people from developing world want to be inside America's 300 million people bubble. Even with a 10x inefficiency, there will be twice as many talented people outside this bubble than inside it. So, the only way for the bubble to maintain its superiority is to keep skimming off the top. At 140k employment based green cards/year, that's 0.1% of the children born around the world that year. So even with another 10x inefficiency, the US would only allow the top 1 percentile of the whole world in.

The US wants this top talent. Because at their caliber, they are going to outcompete the US, and fundamentally alter unipolar power structures that give US its modern form. We're already seeing this with China. Now that the US has stopped having the same appeal to top Chinese candidates, Chinese geniuses now build within China, eroding America's control in every industry, one at a time. Eg: The world's best AI institutions are all Chinese [3]. The institutions didn't improve that much. It's just that America stopped being able to poach their best away.

Wages WILL be suppressed. The competition free utopia of the Boomers and Gen-Xers was only possible because the US emerged as sole superpower of the 20th century, while Asia rebuilt from scratch. Now that the world is stabilizing again, American wages can't hold up to scrutiny from the rest of world.

> the complete abandonment of on-the-job training, falling tertiary education standards

Not sure what immigration has to do with any of this.

> I don't know how bad it is in the US, but in the rest of the West, it's been a disaster.

If you're talking about Canada and Europe, that's a whole another story. Yes, their mass immigration programs have been unmitigated disasters. But, you can't plainly extrapolate that to the US. The specifics matter. On that note, I wish you were more specific about what kind of immigration ?

Skilled vs unskilled

Legal vs Illegal

Vagrant men in their 20s vs Families

Religiously conservative vs liberal

Tolerant vs Fundamentalist ?

It makes a difference.
