It wouldn't necessarily be corporations, but syndicates. Right now collusion and dumping are kept to a relative minimum, compared to what could be. It would be like what happened in Steinbeck's, "The Pearl," novella. Every pearl buyer gave an extreme low ball for the gigantic pearl. There will only be one ruling class with 100% of the econony's money. It doesn't matter if even no money is exchanged and a pure left anarchy. There will be a means of wealth measurement. Capitalist, socialist, communist. Doesn't matter. We'll always have the elite. Jesus got it half right. The poor will always be with us. It doesn't matter if the basics are provided for nearly all. Do you want all poor who serve one master in pure socialism or communism. Or do you want to be the lesser master of some too?
