From Senator William Roths Book "The Power to Destroy"

In our day we are seeing the net effects of taxing everything in sight...
When you tax a man’s income, his income goes down. The power to tax is the power to destroy.
When you tax a man’s income, you are taxing his employment. So unemployment rises and employment goes down. The power to tax is the power to destroy.
When you tax a man’s ability to work, he works less. True productivity goes down. The power to tax is the power to destroy.
When you tax a man’s work, you tax the chief source of his freedom. “Six days thou shalt labor...” The power to tax is the power to destroy.
You see, a government can tax all kinds of income for all kinds of reasons.
But not Liberty.
