The consumption tax doesn't target investments and savings. It only taxes consumption. When you buy an item, you pay a tax to acquire it. We're already familiar with such a tax: the sales tax. I find its implications less troubling than the income tax, which invades my personal privacy and assumes the government has first claim to my assets regardless of whether or not I spend them.
"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
