Why do owner of the business let the government own their business? Even if they offer a big cash i will not sell my business to them because it is my assets if i lose it how i can earn? Even if they paid me what will happened to me if the payment for my business is gone? I think the business owners are liable what happened to your country.
One possibility (and this is all imagined of course) is that the government opens new businesses to compete with private ones and drive them out by offering taxpayer subsidized cheap prices. There are many ways.
