Though I would throw out the following thought.about why government can’t run an economy. The object of the truly wealthy is to make a product or provide a service that people want to buy a a price they can afford. This means that the lower the price more and more people can buy the product or service. The more products that are produced or services are delivered the cheaper the product or service become because of economy of scale
However once the government gets involved they have to write regulations and specifications for the product or service. This causes the cost of production of the product or the delivery of a services to increase which causes some small amount of people not be able to buy the good or service they desire. This lowering the production cause a slight increase in the cost of production added to the additional cost caused by government. This will eventually lead to a situation where the product is not generally available because of its cost. And since there is not enough profit in the providing of the good or service the provider go on to do something else.
