What's not especially useful in my opinion is wealthy people who are failing in their company calling up their buddies to get more funding to buy up other companies that are doing something useful and successful when your own product is failing. Regardless of this case, we are all better served - & society is better served too - by new companies creating technologies and solving problems that succeed or fail on their own merits; the group that is not better served by this is people who succeed through influence peddling and connections to other rich people.
