The problem is maintaining competition. Another thing those MBAs salivate over is the idea of buying out the competition, and their squeeze-the-company-dry method can give them just enough money for just long enough to buy a competing business to run into the ground when the original one starts to give out. Like I said, parasitic fungus: move to a new host as the old one dies. Keeping them from spreading can only be accomplished by stronger government regulation than many people seem willing to see in place, alas.
