First, let me begin with a few definitions.
Money - is the value somebody is willing to pay for a product/service.
This means, if you create a product, you create money. If you enhance a product, you enhance the value and hence create money. If you work for a company, you enhance its capability to produce, hence you create money. The amount of money is not a fixed value within a country (or world, city, family). It increases if you produce and falls if you dont.
Government - is a system formed my people to make and enforce laws that ensure our social interactions remain peaceful and just.
Tax - is money collected by Government from its citizens for its expense.
The following definitions are intentionally very simplistic to allow for later interpretations.
