From my perspective, a couple of problems crop up during this thought experiment.
Firstly, one of the reasons that grand social planning experiments which grant enormous powers to a centralized governing body, is that no one person (or a handful of elites) can truly know all possible situations of every person under their control. Their grand designs may work out for 99% of the population, but the remaining 1% suffer. The social planners try to solve each problem that crops up by adding more and more complexity to the system, and further reducing the individual liberties of the populous. “The more the plans fail, the more the planers plan”.
So for this idea to even have a chance of working, the machine in question would first need to be a super intelligence capable of doing what has been proven again and again cannot be done by a single benevolent dictator or handful of elitists. Additionally, it would need access to enormous amounts of data to be able to make choices which negatively impact the fewest number of people possible.
Secondly, who gets to decide what are the “better qualities” of a human being? Just as one example, from the tone of your post (correct me if I am wrong), it seems as though you consider capitalism to be a bad quality (“buissines and money overtook the world”). I on the other hand think that the concept of private property is a basic human right, and business is the natural outcome of that right. You and I would probably disagree about whether or not this was one of the “better qualities” that the machine should be endowed with.
There are many, many other points besides capitalism, which would be difficult to come to a universal agreement on whether or not to endow the machine. And once a decision is made, then I suppose the populous who disagree just have to shut up and color? Is there any recourse in this society for individuals who have moral objections to the rules of the society? And how are those rules enforced when individuals decide to disobey them?
Just some thoughts I had when reading this… I expect you were coming at this from a philosophical perspective rather than a political one, so hopefully I haven’t offended
