It's too true.

As someone who was one of the indentured servants described in the comments, I can vouch for the accuracy of the entry.

Some telling comments about class from 'mobocracy'-

"Missing from this is the cultural component to this. My wife is a senior marketing manager at a company whose products and services involve geotechnical engineering.

We got into a debate about H1B workers and the "shortage" of qualified engineers. I asked her why they didn't pay more to hire the engineers available and she said they were "too expensive". When I asked her why they didn't cut her salary to balance to cost of engineers, she gave me a pretty shocking answer -- executives and marketing personnel "always" need to be paid more than engineers because they are intrinsically more valuable.

In my opinion this explains a lot, and it seems cultural. Even though the products and services DEPEND on engineers, there's some kind of ceiling on their value relative to managers and marketing personnel. I think this attitude also explains the death of manufacturing -- these people and those jobs are less valuable in the same way that a commoner is less valuable than an aristocrat. It's class driven."

And this one by THR -

"An H1-B employee and their family can be forced to leave the country within 2 weeks of losing the job the H1-B relies on, even if the person has been here for several years. Houses, cars, furniture must be sold at fire sale prices if they lose their visa. If an H1-B worker wishes to acquire a green card, they can be required by their contracting company to use the company's immigration attorneys. An Indian friend of mine got his green card after 5 years of effort and $25,000 in expenditures.

The result of these conditions is a workforce that NEVER expects a raise and never complains because the cost of dismissal is so high."

I've lived through the latter, and observed the former way too often.
