New Ageism, and its more religious offshoot, the success gospel (and similar movements outside Christianity) all teach that if a person simply believes hard enough, long enough, deep enough, success -- usually defined in materialist terms -- will happen. A term often used is "manifesting."
Its believers, especially of the more Randian/Objectivist wing, are told that if they're hard-headed enough, hard-hearted enough, ruthless enough, long enough, success -- invariably defined in materialist terms -- will happen. A term often used is "libertarianism."
A more accurate term is "Social Darwinism." For New Ageism, a more accurate term is "Social Darwinism with lipstick."
