At least that's the gist of it anyway. So no one can actually "make money" but what they can do is figure out how to tap into the flow of economic services that will get them indirect access to some of the numbers in the database managed by the central banks. At this point there are one of two things you can do which is either do something that enables governments to manage their populations by moving people around and keeping them clothed, housed, and fed (essential services) or you can provide non-essential services like keeping people entertained when they're not working and informing them of what's happening in the world at large, e.g. podcasts and newsletters. The problem is the following, there is no way to get rich from doing any of this because all of these things are saturated with enough people such that the overall money pie is already split between them pretty evenly so none of them are going to end up rich in any meaningful sense. This means the only way to truly get rich is to operate on a scale that no one has thought of before, e.g. Microsoft, Google, OpenAI, Amazon, Salesforce, SpaceX, Dell, Nvidia, AMD, Arm, Raytheon, Saudi Aramco, &etc.
Most of the time people are just fighting over scraps and the best they can hope for is some steady source of income that pays their rent and affords them some basic luxuries like visiting Las Vegas and watching a few acrobatic shows.
The people that are truly rich like Klaus Schwab operate in an entirely different world. Similarly for the executives at big pharma and big tech.
I'd say the game is inherently unfair but it still doesn't prevent people from playing it to the detriment of all the players involved.
