Also there's one and only one defense with respect to abuse either at interviews or after you get the job: having a large stash of money, which allow you to say NO to abuse. At least 5 years runway, entirely on your own "payroll". If you're actually competent, that's more than enough time to pick any skill (possibly starting your own business rather than look for a job using it), if you can do 12 hours per day by your own choosing on whatever you see fit. Don't have those 5 years but only 1-2 or, god forbid, have nothing more than a few months on top of a large amount of credit you have to pay back.... and you're in the 99% percent of desperate and destitute crowd who will submit to anything in exchange for a bowl of soup (guarantee they never break out of slavery). Problem with the solution is that it's a vicious circle: if you don't already have those 5 years of savings, chances are you're never going to save them anyways.
