As you know, the federal, state and local governments have many tasks to address, which no one citizen can organize, settle and cover. For example, we need to spend on national defense, public safety, social security, training, and transport. Federal, state, and local governments undertake these tasks and the financial costs incurred by the taxpayer. This is only possible if each citizen, or both, has to contribute to the expenses. It's just that each of us has to pay taxes. Indeed, my child or family member or friend has received money (child allowance, housing allowance, unemployment benefit, class picnic funding, etc.). Indeed, a few of us will not voluntarily pay taxes. Equity issues in the taxpayers have these ideas, but here it is necessary to maintain the discipline of the state by tax laws.
