Waste disposal is an incredibly complicated process, and it is for this reason that garbage collection franchise monopolies are one area that is a particular exception to the United States anti-trust laws. When one company knows exactly where their runs are, there is less confusion when it comes to trash day.
No, garbage collection franchise monopolies are not good, because there is no reason that there cannot be competition. If people could choose between two or three companies, they would be able to choose which company gives the lowest cost, or provides the best service. It would drive up the quality.
Garbage collection franchise monopolies would be just as bad as having any other company or industry with a monopoly. No matter the type of work or where they do their work the fact that a company can have a monopoly would be a bad thing. We should not give too much power to one company.
Monopolies are bad, it doesn't matter what franchise or business they have monopolized. Garbage collection monopolies could easily be compared to the monopolies of the cable companies. It is a service most people are going to have to utilize, so when a company monopolizes a market they can freely raise their prices without losing business.
