This is why Lefties say "It's ALL Luck!"
Social Insurance and Income Redistribution in a Laboratory Experiment

Abstract: Why do some voters support income redistribution while others do not? Public assistance programs have two entangled effects on society: they equalize wealth, but they also cushion people against random catastrophes (like natural disasters). The authors conduct a laboratory experiment to determine how individuals' responses to the environment are related to their self-expressed political ideology and their self-interest. The findings support the hypothesis that ideology is associated with a person's willingness to use redistribution to reduce income inequality that is caused by luck, but it is not related to preferences for inequality that are not related to luck.
