For both a good summary of "conservatism" and also a clue about how much conservative Judges are distorting the Constitution, take a look at what the pro-Slave Confederate rebels changed in their version of the Constitution. They cut "more perfect union" and "promote the General Welfare" from the preamble to start: because Conservatism is about Austerity not Prosperity. And in the body their main changes are protecting slavery and prohibiting government assistance for economic development. No country has ever become a prosperous manufacturing nation without government protection of and assistance to industrial development - and the Confederates knew that. The leaders of the Confederacy wanted a nation composed of slaves, poor white people to be sharecroppers, overseers, and cannon fodder, and a few wealthy white landowners. They did not want their cotton business, based on cheap and slave labor to pay any taxes.
no bounties shall be granted from the Treasury; nor shall any duties or taxes on importations from foreign nations be laid to promote or foster any branch of industry;The Confederates knew, as did the earliest American governments, that protecting manufacturing against "dumping" and "fostering" new technologies and methods was essential for growing local industry. They just did not want manufacturing industries offering workers higher wages and creating a middle class that would have scruples about slavery. And they were rich already, they did not want to share costs of giving the country a prosperous manufacturing economy and providing opportunity to the insolent lower classes. Low taxes and low wages have always been the Confederate goals. The Commerce Clause of the constitution which is the basis of both government intervention in the economy (like cleanliness standards for meat packing plants and health care reform, and preventing child labor) was also a target. The Confederates didn't make up "interpretations" to support their economic ideas (like Scalia does), they just changed the wording and added this statement.
; but neither this, nor any other clause contained in the Constitution, shall ever be construed to delegate the power to Congress to appropriate money for any internal improvement intended to facilitate commerce; except for the purpose of furnishing lights, beacons, and buoys, and other aids to navigation upon the coasts, and the improvement of harbors and the removing of obstructions in river navigation; in all which cases such duties shall be laid on the navigation facilitated thereby as may be necessary to pay the costs and expenses thereof.Federal government spending on roads, trains, or education? Not in the Confederate states.Why if the common people get educated, then they might wonder why it was right for them to be living in tar paper shacks and getting scraps from the plantation mansion. That would be insupportable. And that is the heart of "conservatism", Confederate or "Republican".
