Wouldn't it be better to use a cheaper robot and just donate your extra cash to the old people? Is it that you want to compel all other less generous customers

Wouldn't it be better to use a cheaper robot and just donate your extra cash to the old people? Is it that you want to compel all other less generous customers to pay for the old people too, and a robot would take away that requirement, which is a kind of tax? Initially, all the extra money would go to the startup, but with competition, it's the consumers that would save. If it actually works.
