The American people wouldn't support it. Even without high sales taxes, consumer spending has been on the decline. If Congress passes a 30% sales tax, then a lot of retailers will end up closing their doors."Kevin McCarthy has proposed a vote on a proposal called the Fair Tax, which would abolish the current federal income tax and replace it with a 30% national sales tax. 30 percent."
No retailer, corporation, or business in their right mind would support this.
The day they pass this is when I'll immediately only buy food in stores and nothing else. You know what, maybe they could pass this. I might actually save a lot of money in the long run because my spending will DRASTICALLY decrease.
