Because they’re seeing how that “replace you with cheaper and more easily manipulated worked in 20-30 years” is working now. They might try relying on breeding, but when that falls short (like when all the boomers suddenly start retiring), they’ll realize they can’t trust us to produce our replacements.
If they keep the workforce young and immortal, they can have unlimited workers. No one can demand more money because they can replace you with one of the hundreds of drones waiting in the wings. So we’ll all be kept young and desperate.
