Companies are paying absolute minimum they can. It is only rational.
The problem is with expectations. A lot of H1 workers are used to a much lower quality of life than native workers. US graduate would want to have a 40 hour work-week, separate bedroom, 401k and such. For a foreign worker from a less reach region 401k and medical are not a requirement, sharing a bedroom with 3 other guys is not an issue. Working round a clock is fine as long as you can send money to your family back in the old country. Oh, also in US you can afford a car that will make you look super-successful on social media.
Do you really want to drive down quality of life for everybody.
