This kid is the difference between idealism and reality. In an idealist world, automation would fund UBI, which would fund a higher quality of living for everyone. Which is effectively parallel to what you’re arguing here, in it’s fundamental mechanics. As you can probably see, many Western nations don’t have UBI. Why? Because automation doesn’t give back to the people, automation provides more wealth to a few corporations and individuals. The same thing goes with delivery robots. It largely benefits the corporation, which can cut additional expenses by not having to pay a human. Where does that money go? It goes to line someone’s coffers. If it was taxed appropriately, then that money could go back into the public, but it doesn’t. That’s the reality. The reality is that no matter how much of an idealist you want to be, the world around you dictates how things work, not your ideals.
