The law reads VERY CLEARLY that income from payment for labor services are taxable.

No, the law states that income from payment for labor is an ITEM of GROSS INCOME. Gross income != Taxable income.

Taxable income is stated to be GROSS INCOME less allowed exemptions and deductions.

You are merely begging the issue, and have no basis to stand on. Compensation for labor or services in the United States earned by United States citizens is not excepted from the inclusion in Gross income or calculation of "Taxable income". In fact it is expressly stated to be included into those calculations.

Your items/sources argument is a totally dead issue, as all income has sources and all sources unless expressly excluded by statute are subject to the income tax law.

" The following items of gross income shall be treated as income from sources(activities) within the United States"

That is the only sentence needed to be understood; "items of gross income shall be treated as income".
