The only thing that has ever prevented Congress from levying both income and retail taxes at the same is the same thing preventing them under the current income/payroll taxes system and would be preventing them from doing so under a retail sales tax only system.
The American electorate would politically hang any politician so foolish as to try such a dumb move.
The portions of the income tax that was upheld as valid by Flint vs Tracy was held to be constitutional by Pollock v. Farmers as well and would continue to be Constitutional even if the 16th amendment were repealed tomorrow.
POLLOCK v. FARMERS' LOAN & TRUST CO., 158 U.S. 601 (1895):
- "We have considered the act only in respect of the tax on income derived from real estate, and from invested personal property, and have not commented on so much of it as bears on gains or profits from business, privileges, or employments, in view of the instances in which taxation on business, privileges, or employments has assumed the guise of an excise tax and been sustained as such."
- "If that[rents from land] be stricken out, and also the income from all invested personal property, bonds, stocks, investments of all kinds, it is obvious that by a r the largest part of the anticipated revenue would be eliminated, and this would leave the burden of the tax to be borne by professions, trades, employments, or vocations; and in that way what was intended as a tax on capital would remain, in substance, a tax on occupations and labor. We cannot believe that such was the intention of congress."
- "We do not mean to say that an act laying by apportionment a direct tax on all real estate and personal property, or the income thereof, might not also lay excise taxes on business, privileges, employments, and vocations. "
- Our conclusions may therefore be summed up as follows:
First. We adhere to the opinion already announced,-that, taxes on real estate being indisputably direct taxes, taxes on the rents or income of real estate are equally direct taxes.
Second. We are of opinion that taxes on personal property, or on the income of personal property, are likewise direct taxes.
Third. The tax imposed by sections 27 to 37, inclusive, of the act of 1894, so far as it falls on the income of real estate, and of personal property, being a direct tax, within the meaning of the constitution, and therefore unconstitutional and void, because not apportioned according to representation, all those sections, constituting one entire scheme of taxation, are necessarily invalid.
- Mr. Justice WHITE, dissenting.
16. The injustice of the conclusion points to the error of adopting it. It takes invested wealth, and reads it into the constitution as a favored and protected class of property, which cannot be taxed without apportionment, while it leaves the occupation of the minister, the doctor, the professor, the lawyer, the inventor, the author, the merchant, the mechanic, and all other forms of industry upon which the prosperity of a people must depend, subject to taxation without that condition.
Yeah, you're right. It really boils down to 'transparency'.
Once people can see who might be laying a smoke screen, there won't be many more smoke screens.
TRANSPARENCY! That should be the Fair Tax Motto.
They could even call it the Transparent Tax. No more shell games, just clear vision of who is taxing what.
