RE TAXING .. as still much debate abounds in other places on that ..
"Article I, Section 8, Clause 1 of the United States Constitution, is known as the Taxing and Spending Clause. It is the clause that gives the federal government of the United States its power of taxation. Component parts of this clause are known as the General Welfare Clause and the Uniformity Clause." http://en.wikipedia.org/wiki/Taxing_and_Spending_Clause ..
again . to Madison and Hamilton, coauthors of the Federalist, re taxing, and the interpretation of the General Welfare Clause .. Madison's narrow vs Hamilton's broad, and to, Jefferson, siding with Madison's narrow interpretation.
Note: Hamilton's broad interpretation: 'taxing for the general welfare' of the GWC means taxing for the regulation of commerce, and predominates in case law today.
Madison's narrow view is unusual compared to most states and other countries.
Study note list .. LOL .. please correct any stuff-ups ..
