Good article. We currently spend $100 billion just on compliance - again, that money could be going towards purely productive measures for the economy.
Class envy, jealousy, hatred, etc. fuel our tax policies.
One thing the article doesn't mention though is that the first income tax passed under the tyrant Lincoln was correctly struck down as unconstitutional.
Another point:
Eliminate the Income Tax and You Still Have the Same Federal Revenue as 10 Years Ago
Ron Paul has said this several times, and it turns out to be “mostly true,”
according to this site. It would be nice to eliminate those other taxes as well, but it does put into perspective how much the era of big government is not over.
