I was guilty of an overly broad generalization. Not all Republican groups or individuals are focused on exactly this point.
However, over the past two thousand plus years, representational government systems have had a very strong tendency to breed a political force devoted to preventing the majority from using their majority power to distribute the benefits of society anything like equally. Wealth is the obvious benefit to be hoarded, but, in truth, power is probably even more the point. However, since extreme wealth can almost always be transformed into power, it’s not that important to distinguish.
This protect-the-elite force has been the power behind the Republican Party for time out of mind, and their central goal has never really changed.
They have made tactical adjustments. When most of the markets were internal, they were a little more willing to compromise on monetary matters, as long as power arrangements remained secure. When the standard of living exploded upward under New Deal conditions, the successful wing of the party (not Taft or Goldwater) realized that New Deal arrangments could not be fought in a direct, head-on manner. When a propaganda war with international Communists threatened, they saw value in lending significant (but covert) aid to the various rights movements.
But international Communism is not longer a threat, internal markets are no longer all that essential, and very few voters feel the New Deal (or Great Society) connection to vastly improved lives, so this has changed the calculations of that central power group of the GOP.
Add to that the fact that their campaigns to divide the have-nots have been very successful at motivating have-nots to come into their tent under the claims that other have-nots are getting a better shake than they are.
So… in truth, their goal is neither to make everyone’s standard of living go up, nor to make everyone’s standard of living go down. Their goal is their own wealth and, especially, their own power.
But they certainly consider it abhorrent that government is supposed to be looking after people. Whether it’s a hurricane or old age expensive health needs or an economic downturn, as a matter of core principle, they feel that people are responsible for themselves, and that things like social security or occupational safety laws or guaranteed health care are anathema. Because that boils down to power, the idea that there are limits to what those at the very top can horde for themselves.
