 So, for example, if we assume that natural endowments and the willingness to use them are evenly distributed across children born into different social classes, then within any type of occupation (generally specified) we should find that roughly one quarter of people in that occupation were born into the top 25% of the income distribution, one quarter were born into the second-highest 25% of the income distribution, one quarter were born into the second-lowest 25%, and one-quarter were born into the lowest 25%. Since class of origin is a morally arbitrary fact about citizens, justice does not allow class of origin to turn into unequal opportunities for education or meaningful work.
