What prevents the front-line workers to get a software engineering jobs? I know that not everyone should code, but for those who have the opportunity and intelligence for it and liking it, should. SWE jobs are now favored among immigrants (poor and wealthy), because this is their only chance to make a dent in US living expenses. I am one of the poor immigrant (yes I know how it feels working $7.5/hr scrubbing a restaurant that just closed by the health department using bleach while kneeling all day), now having $300k TC, and my entire family are either divorced or single, and all female. I could send money to them in my home country and still have more than enough for me here. I definitely won't want to get paid lower.
