You're looking at the wrong side of the equation. We don't want to reduce their economic advantage we want to use it to make life better for all workers.And that you cant see how strong advanced AI on a completely autonomous mobile robot (that can be bought for about $1500 and never sleeps, never takes vacations, never takes maternity leave, will never unionize, etc) wont displace human workers unless something is done to reduce their economic advantage speaks more to a problem entirely unrelated to the subject itself.
