Could you define how the greed of the businessman is a greater evil than that of the mayor?
Let me go a step further on justifing the businessman over the mayor. First off, I admit that all greed is evil.
However, my problem is this: Who is more likely to understand the intricacies of water management? The businessman who has most likely employed people as experts in the field, most likely has dedicated his own life to the business of water manage, or the mayor who may or may not understand anything concerning the field, other than knowing that it's a local hotbutton issue?
After all, a mayor is a leader that must rule over many, many fields and may not have the expertise in the fields required. But the businessman absolutely should, afterall, running a business successfully requires knowledge of the field.
I feel this is why we have so many issues with reform in the system. Politicians come from very diverse backgrounds and careers, and usually are campaigning to change something they may, or may not, have any idea how to fix at all. They may get experts to tell them, but they truly have no idea about the field themselves. Furthermore, the experts they hire may be favorable to his viewpoint, rather than that of a market-neutral perspective.
Business control monopolies because they are good at what they do. Wal-Mart is not becoming a retail monopoly because it was legislated. They are doing it because Sam Walton was a friggin' retail genius that knew how to wheel and deal to give us 'always low prices'. Microsoft has become a monopoly because Gates broke the PC mold of offeringing a verticle solution for operating systems via proprietary means, and afforded customers and retailers a more robust solution.
However, a politician rarely crafts a bill because they are experts in the field, nor gain power through the understanding of the problem, but the promise that they understand the problem. This has given us such American wonders as the public education system, Social Security, and Medicare.
You are indeed correct that other countries may be able to do it more efficiently. But that does not mean that if we adapt to their system we become as efficient. We are different people. What about our public education system is so radically different that we spend twice as much on a government system and get less quality? Mind you, federal education has been around for decades.
