Essentially, we just don’t want to offer the services and benefits we could vastly more easily provide now. Like most things in this world, it’s a choice. And we choose not to do so. For no good reason, either. Nearly all of what we once were able to do as a civilization we could do now and it would benefit everyone. But in the descent into zero sum thinking that has occurred for an enormous variety of reasons, people are convinced it’s more worthwhile to hurt their neighbor rather than to help them.
This, they incorrectly believe, will raise them up. The reality is that it drags them both down. As we’ll see soon enough.
