Well a income tax and social security were unconstitutional.
SS is a pay as you go system. In other words there is not proof that a dollar in is a dollar out. Because of this you are paying for someone else based on the currently known limit to SS.
ie. A later retirement date to give time for the current work force to pay for your retirement.
Because of this your grand children will be paying for your sins as anyone who is currently working is paying for the sins of the ones retired now.
The part that makes it unconstitutional though is that you are forced to pay it by law.
Generational Tyranny in the end.
As for income tax, it's a shady prospect, it always was. I have a foggy memory of the history I just remember a few politicians wanting to put one in but Americans rejected it due to the similarity with a monorchial taxation.
The end result is that it was passed in like 1910 I forget how but I remember getting a shady vibe from reading the bio's of the men involved in the decision. It shouldnt have to be said but the income tax wasn't brought in for the betterment of the American people.
IF income tax relieved property taxes and so on then it would be in favor of the people to relinquish 30% of their income.
