How could changing how money works change people's wealthiness when big producers hold all the production causing all work and purchase power go through them? If you manage to save anything, they will make you starve until you don't have any of it left anymore.
Because at this point money itself is a technology and a product. Corporations don't want people to be poor; they actually want the opposite so that they can extract more money out of them. The idea behind crypto doesn't extend to just money. We are eventually supposed to decentralize all the means of production. Which is obviously a very tall order that could take decades.
On top of all this most products and services are completely optional.
No one's forcing us to go to an expensive restaurant or buy a new phone every year.
This computer is from 2016 and it still works awesome.
