I used that as an example. Discrimination lawsuits might be feasible against big companies but smaller ones might look and not hire you by giving you a bogus reason, or no reason. Even if someone sues them 4 years later, your rent is due by the 5th of next month.

They are many other things one did 10-30 years ago that can stop someone from getting a job (minor criminal convictions, college pranks, marijuana arrests etc etc)
