Employer-dependent healthcare and visa status are powerful tools of control. Let's also not forget sky-high housing costs, ensuring an astronomical savings burn rate when unemployed.
Yea; but I'm a programmer/engineer. Last time I needed a job, I had a contract for $15k that month within two hours, and an interview for a full time position by the end of the day. People in our position have the power to do things like that, and we should use that power for good.
Congratulations on the good fortune, but I’m afraid your ability to get another job instantly is not shared by the vast majority of practicing software engineers, particularly visa holders. Even in these top companies, there is a relatively small number of developers who actually have this power!
That might be true. I only really know my own experiences. I don't even have an engineering/CS degree, and have just taught myself everything. But, maybe I have some special experiences that others haven't had.
