Constitution: "The Congress shall have Power To lay and collect Taxes"
Thank you for a coherent response.
But you left out a major part of that quote.
In full, that part of the Constitution says:
Article 1, Section 8:
"The Congress shall have the Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States; but all Duties, Imposts, and Excises shall be uniform throughout the United States;
"To borrow Money on the credit of the United States;
"To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes;
"To establish a uniform Rule of Naturalization...."
"Congress shall have the Power To collect Taxes to provide for the general Welfare of the United States [and for other listed purposes]...."
In fact, the Clause is a statement of what government can spend tax money on. Not a permission to do whatever they wanted under the vague guise of "helping people". So, it is actually a restriction on government, not a broad permission. The complete clause really means, that the government can collect and spend tax money, but that anything spent to help people, must be applied
evenly to the entire population, and cannot be "targeted" at certain groups.
