Boss doesn't believe in supporting people who can't work. Everyone will eventually be unable to work, whether due to age, illness, some kind of trauma, whatever.
Is it really a good idea to work for someone who wants to ensure you can't even live once you stop making them money?
That leaves me with even more questions. If that is actually what this person is thinking... what about children? What if someone gets sick? Or breaks something?
Not to mention that the downvotes here make absolutely no sense.
