Individual Income Taxes...

"The most damaging aspect of the Sixteenth Amendment is the fact that it vitiated the unalienable rights provided in the 4th Amendment. This is the amendment which protects privacy--privacy of the home, business, personal papers and personal affairs of the private citizen. None of these are disturbed by a poll (head or capitation) tax because it is so much per person regardless of the circumstances, but when the tax is based on income, the IRS is assigned the most unpleasant task of making certain that everyone pays his fair share. This task is physically impossible without prying into the private papers, private business and personal affairs of the individual citizens. By any standard, it is a miserable assignment. Furthermore, it is impossible to run audits and surveys of all taxpayers and so the audits seldom check more than 2% of them."

"The income tax is fulfilling the Marxist prophecy that the surest way to destroy a capitalist society is by steeply graduated taxes on income and heavy levies upon the estates of people when they die."
