Under Bush, deficit spending has ballooned out of control. The entire notion that government can or should do anything becomes quite absurd. There are an infinite number of ways to organize ourselves to do things. If someone claims that a particular way is the only way, then they have to demonstrate that none of the other ways work - including all the ways we have never thought of. I doubt if anyone can demonstrate this.
Human beings are necessary to do certain things.
Some might still argue that it's not the people in government as such that are necessary, but the structure or institution. This is essentially an argument that some form of management and coordination is necessary. Whatever management and coordination may be necessary can be provided much more effectively by people cooperating voluntarily for mutual benefit. The reason why people in government insist on using coercion is because they want your money without providing you with commensurate value in return. They essentially want to get as much as they can from you while returning little or nothing.
