From this video by right-populist and noted loser Dimmy Jore
Honestly there isn’t a child on the planet who doesn’t contribute more net good to the world in a single day then Elon Musk has in his entire adult life. And I’d rather spend a whole year looking after the least pleasant children I worked with all by myself then spend 5 seconds in Musk’s presence.
So yes, I agree, describing Musk as a “manchild” is an insult to children.
Some people do have negative value to society, such as derivatives managers. The person mopping the floor in the office has positive value that the derivative manager wants to nullify to public perception by lobbying and propagandizing how little worth the floor mopper is.
Similar deal with hoarding the metaphorical toys and having actual contempt for children, including his own.
