Generally speaking, money represents an investment of time and effort on the part of the wage earner. It not only enables the acquisition of goods and services, but it can also provide greater freedom over how your time is used. An example of this can be seen in families today. If one married wage earner brings home enough after-tax income to provide for their family, that family is free to choose whether both should work outside the home or not. Without adequate take home pay from one income, they are not.
Taxes can also affect our ability to give to others.
It is important to remember this when you consider the issue of taxes. Taxation is not only the confiscation of money from people, but also the confiscation from them of what that money represents. Government taxation takes time, labor, resources, and freedom from people and their families with every tax extraction. It takes from them portions of their lives. The framers understood that the nature of government tends towards expanding and confiscating as much resources as it can.
