Why private companies may become more popular than public companies in the future?

My prediction is that in the future, private companies will become more and more popular than public companies because of several reasons. Firstly, I always expect the wealth gap among the world population will become wider and wider because technology is able to take over more and more basic jobs from our human beings and capitalists are more capable of accumulating their wealth. When the global wealth becomes more concentrated in a small group of people, the targets for companies to seek investment become narrower. Seeking investment in the public financial market becomes less attractive, as having access to a big market does not necessarily increase their chances of being invested due to the limited number of potential investors. Under such circumstance, one major advantage of becoming a public company is not so significant anymore. Secondly, private companies have many advantages in terms of management. Entrepreneurs would like to have as much control over their companies as possible; therefore, when there is no difference between staying in private and going public in terms of financing, they are highly likely to make their companies stay in private. Thirdly, in the future, not only wealth gap can make small investor start to disappear, the technology and the gravity of large capital will also push small investors out of the market. When there are only large investors existing in the market, these large investors could be very willing to shut down the public market, as the existence of some small investors could increase their costs of buying and selling, when shutting down the public market, they have the resources to set up direct connection between the sell side and the buy side. When they are making large-scale deals, the costs of setting up such connections are relatively small.
