Equality will always be prevented as long as we're allowed to exercise free will. A wise man said, "Differences in habits and attitudes are differences in human capital, ...and such differences create differences in economic outcomes."

Besides, the 2nd sentence of the Abstract shows they begin by labelling the perceptions of others as inaccurate. This corrupts the rest for me:

>Only when equality is increased within their ingroup, instead of between groups, do advantaged group members accurately perceive it as unharmful.
