Are you saying that society has not been striving for an "effective" government. What has the collective voters been doing, if not trying to make the government more effective?
The reason I say small, is that it limits the power of corporations to effect government. When you centralize power, you centralize corruption, and it becomes far less expensive to corrupt. The reason there are so many lobbyist, is because its the most effective use of corporations time and money. There are very important roles for a central government, and that central government needs to have authority. With out that, you get free loaders and it all breaks down. But, at some point, the incentives for government are to benefit the corporations and organized wealthy, and not the voting populous.
So while you may be sick of hearing people wanting smaller government, know that advocating an effective government has not been working so far.
