Is it possible for everyone in the world to be wealthy? If it is possible, how can it be done? What would such a solution look like?

I think it is possible. But first let's look at what wealth is. In order for there to be wealth we need two things, a product or a service with exchange value, and a distribution system on that product or service.

Let's take a look at the first thing. To be wealthy we need to produce a product or perform a service on some level. We could inherit the product or service, but there must be one. Examples of products would be anything from soft drinks to cars, with all that is in between. Examples of services would be from tv or movie actors, to lawn care specialists, and more.

The second part is the distribution system. This is the system that gets your products or services to those who want them. Today the distribution system is the hardest system to put into affect. How do you find that one eskimo who needs an ice cube? Look in the desert for an eskimo out of place.
