rathi, having worked for the federal government I know exactly what a portion of the federal government does.
Here are the two main problems that you just demonstrated...
1. You have trouble understanding the idea of
a taxpayer division of labor. As a taxpayer you wouldn't have to know how many federal departments there are any more than consumers have to know how many corporations there are. You would just pick a few areas that you really care about and concern yourself with those areas. Or...you could just give all your taxes to congress if you felt overwhelmed by the prospect.
2. If you had even the basic understanding of knowledge requirements then you would know that the premier Nobel prize expert in this area was Hayek. You would have already read his essay on
The Use of Knowledge in Society and understood that the market operates on the basis of partial knowledge.
Given that you lack a basic understanding of how the invisible hand works...it's clear that you don't need to know how the invisible hand works for it to work. But you do need to understand how the invisible hand works in order to understand why taxpayers should be allowed to directly allocate their taxes. Right here you have an epic opportunity to be way ahead of the curve...so why not take the time to thoroughly read Hayek's essay.
Honestly I had to carefully read through it several times before it really made sense to me. That's when I realized that he was saying pretty much the same thing as Buddha's parable of the blind men and the elephant. We all have some information but nobody has all the information. By allowing taxpayers to directly allocate their taxes we would be incorporating an infinitely greater amount of information which would produce an infinitely more efficient allocation of limited public resources.
Without understanding this concept you'll never truly grasp why socialist systems failed. If you do grasp this concept then you'll understand that socialism could totally succeed as long as taxpayers could directly allocate their taxes.
