It's a very effective system for quickly concentrating all the owenership of ice cream machines in the hands of the people who are best at deciding when, where and how much ice cream is needed as measured by profits - even if they personally don't have much when they're starting out. And if there is a better measure than profit I'd like it to be proved up in a country I don't live in because those experiments usually result in ice cream shortages.

The concentrated ownership results in graphs a lot like the one in the linked article.
