It's a race to build self-repairing bots. Once the wealthy have it, they can just go ahead and let most people die.

self-repairing is only a small part.

bots would have to be just as useful/cost-effective as poor humans. Apparently manual labour at $2/hr is cheaper than robots still.

If the environment is too hot for a human to work outside, the labor cost goes to infinity as the work will not be completed even if somebody takes the money

we have remote controlled robots even today for such things. still requires a human operator.
