if I’m not going to do it, someone else will happily do it
This "justification" works for everything, from parking on the disability park spot to genocide.
Having said that, my first task at a new job in '94 was "you see these three workers counting, stacking and feeding the product into the packing machine? You'll design a stacker to replace them". "ah, three workers three shifts, so you're saying my first task is to make 9 people jobless?". "yup, but we'll replicate it to other lines, so...".
Someone would do it anyway.
