I have seen/heard several rich people suggest a willingness to pay higher taxes, suggesting that all rich people should pay more. Its unclear that more taxes will stop excessive spending. So, if folks like Buffet fill compelled to pay more taxes, perhaps they should just contribute to reducing the national debt. Apparently this is easy to do by sending a check to the Treasury. If you are interested, Make your check payable to the Bureau of the Public Debt, and in the memo section, notate that it is a Gift to reduce the Debt Held by the Public. Mail your check to:
Attn Dept G
Bureau of the Public Debt
P. O. Box 2188
Parkersburg, WV 26106-2188
