Unfortunately many terrible people like the second solution of just killing off the unemployable in various ways.

No communistic / socialistic people actually believe that garbage, the whole point of communism and socialism is to provide for people's basic needs. I've never once met someone that seriously talks about communism who would actually suggest using people like that. And communism doesn't mean democracy, the best systems are obviously ones where people have equal opportunity to voice their opinions and needs equally.

It's actually a bad faith argument by capitalists who struggle to see the use of a human being beyond how much labor they can be used for.
