"What, then, was “conservatism” struggling to conserve? It was not capitalism, an idea that leading figures in the movement shied away from even talking about. They wanted to preserve the status quo, a system with elements of freedom and welfare statism, which Rand called the “mixed economy.” What “conservatives” projected was a “guilty evasiveness,” an “apologetic timidity,” and, crucially in Rand’s analysis, a “peculiarly non-intellectual, non-philosophical attitude” in their positions."
