Alexander Hamilton took a broader view of Congressional spending power in his interpretation of Article I, Section 8

“The Congress shall have power to lay and collect taxes, duties, imposts and excises, to pay the debts and provide for the common defense and general welfare of the United States; but all duties, imposts and excises shall be uniform throughout the United States;” The Constitution of the United States of America, Art. I, Section 8.

The Court has adopted the Hamiltonian view for several decades now... See Fullilove v. Klutznick, 448 U.S. 448 (1980)424 U. S. 1, 424 U. S. 90-91 (1976); United States v. Butler, 297 U. S. 1, 297 U. S. 65-66 (1936). Congress has frequently employed the Spending Power to further broad policy objectives by conditioning receipt of federal moneys upon compliance by the recipient with federal statutory and administrative directives. This Court has repeatedly upheld against constitutional challenge the use of this technique to induce governments and private parties to cooperate voluntarily with federal policy. E.g., California Bankers Assn. v. Shultz, 416 U. S. 21 (1974); Lau v. Nichols, 414 U. S. 563 (1974); Oklahoma v. CSC, 330 U. S. 127 (1947); Helvering v. Davis, 301 U. S. 619 (1937); Steward Machine Co. v. Davis, 301 U. S. 548 (1937).448 U. S. 473-475
