Flat tax blowback

[KikoSanchez]

According to Neil, the flat tax would basically mean a 22-30% sales tax. I have yet to read the manual for this proposed tax plan, but I think it may have a practical problem for the economy. Our economy is ever-growing largely because of our consumer society and people's constant buy, buy, buy, spend, spend, spend mentality. Do you not think the psychological effect of a 25 or 30% sales tax would make people less willing to shop as they currently do? This may be good if people actually invested this money instead, but nonetheless it would be bad for the economy.
