I am ok with my effective tax rate as well. Investing in the services of a good CPA is money well spent. But, it's all of the other taxes that get you: phone, cable, internet, power co., gas, storm water runoff, taxes if you own a business, surcharge to use a credit card for services at some businesses, etc.
I have no problem paying 23 percent in sales tax. I don't spend 100,000/yr., so I will be paying far less than 23,000 for my consumption, have money to save, play, travel, make improvements to my home and drink expensive wines. I totally am on board for the fair tax....well, because it's fair and it makes sense!
Except you will be paying more than 23%.
A. That rate is too low to replace Federal revenue.
B. Don't forget your state sales tax because unless the tax fairy waves her magic wand it ain't going away.
