There are obviously easily exploited loopholes to enable H1B visas especially for a couple of businesses that hire the most H1Bs.

As long as most countries in this world have median wages well below 33% of the US there will be rampant outsourcing / under the table labor / vastly lower comp H1B roles.

If you truly try to minimize your cost of living the cost to live in the US is surprisingly cheap. Most shit we buy is optional. Rice and beans are cheap, you can find people giving away clothes, transportation can be very cheap and a simple pay as you go phone can be very cheap and be your access to the internet and is fully functional. You can make enough with a job that just pays minimum wage to send enough money home and feed an entire family without yourself worrying about being homeless or going without food.

Immigrants tend to try harder and put up with more bullshit than natives because things are that much better here than back home. Hell, we have food pantries! That’s basically unheard of in most of the world. Billions still struggle to put food on the table outside of the US and western europe. I relied on food pantries as a kid to survive in poverty. My wife is from a third world country and couldn’t believe people would just give food to those in need freely.

I’m not here to bash on immigrants, i’m just pointing out that even the poor in the US generally have more privilege than they could possibly realize. The vast excess of the top 10% in the US is crazy, and the .1% here are so egregiously overcompensated it should probably be criminal.
