My understanding is that Bernie Sanders used to say that mass immigration was a "Koch brothers thing" and his tune on this has since changed to align with "progressive" ideas, but I might be mistaken.
I already know that the right-wing supports h1bs, Trump himself said so.
He recently addressed Congress and brought up the abuse of H1B such as for entry level accounting positions. The program was to meet shortages for highly skilled positions. Now its being abused to cheat new grads out of jobs and depress wages
Even in his most immigration-skeptical era (https://www.computerworld.com/article/1367869/bernie-sanders...), Sanders always acknowledged that some companies genuinely need a skilled immigration program to hire the global best and brightest. And note his line about "offshore outsourcing companies"; the issue's become even less controversial now that the balance of H1B sponsors is shifting towards large American tech companies who genuinely pay market rate.
Not sure what you're aiming to get out of this comparison. Software engineers make quite a bit more at prestigious tech companies than they do at prestigious finance firms in NYC, and prestigious finance firms in NYC extensively recruit people from outside the US. Even if you want to compare engineers in tech to bankers in finance, I'm not sure Goldman is paying all that much better than OpenAI these days.
Why do people think Goldman pays software developers so well? They do not. They pay whatever is required compared to their competition (mostly other ibanks). There is a tiny sliver (less than 5%) of the dev staff who work in front office and are called "Strats". (Some other banks have "Strats" [Morgan?] or put you into a quant team to pay you more [JPM/UBS/etc].) They make about 25-50% more money compared to vanilla software devs in the IT division.
The job of the high paid people in finance at prestigious firms is to look nice in an expensive suit. Know many people in tech with those qualifications?
I'd be good at it but I won't get hired cause I didn't go to the right boarding school.
Tech has its barriers too. Most people I've met in tech come from relatively rich families. (Families where spending $70k+/yr on college is not a major concern for multiple kids - that's not normal middle class at all even for the US)
Regarding the first sentence, it is already true for software developers. You can (and probably will) make more money at FAANG compared to global ibanks in NYC.
TACO Trump himself said he'd reveal his health care plan in two weeks, many many years ago, many many times. But then he chickened out again and again and again and again and again. So that the buk buk buk are you talking about?
