One of the big constant news stories recently has been about UK water utilities constantly flushing untreated sewage into the rivers and oceans near the UK, while raising prices, paying huge salaries to their executives and massive dividends. One solution is to take them back into public ownership.
But another possibility is to make the mutual companies. I worked for a mutual insurance company for a while, and helped it de-mutualize, at which point its prices went up, employees were treated worse, executives made more money and so on.
