Can happen but I suspect that it's unusual for someone to completely suck at every aspect of their chosen area of work. Probably 99% of the time it's mismatched skills/interests. Even in these cases though, firing people is good for them. Maybe they should find something else to do in a different industry. It must be torture to suck at your job every day while simultaneously depriving better suited people of that role/opportunity which you occupy... All while there may exist better opportunities for you in another industry where some other low-performing fool just like you is occupying what should have been YOUR dream job. Of course this is assuming a functioning free market. If the market is overly manipulated, you could find yourself locked out of opportunities which you would be really good at while some mismatched fool has your job and gets paid your salary (which they use to pay a shrink to help them cope with their impostor syndrome...)
