Or your "fair" tax sales.
With the FairTax, mojoron, not reporting your collected sales tax will be quickly spotted ... but then since you've never read the bill and don't know about that you'll just continue looking foolish by making irrational statements.
IAE, the situation is different since with the income tax the government can bring its full resources to bear on the individual taxpayer who is assumed to be guilty until he proves his innocence. With the FairTax, the taxpayer has no interaction with the federal government WRT income (or taxes) and only the merchant who has stolen the federal tax money that he agreed to collect (and is paid to do so) gets the attention of the state tax folks. Even then the retailer doing the defalcation is presumed innocent until proved guilty.
The situations you try to pretend to be the same are totally different.
