Why are white liberals more liberal on average then nonwhite liberals?

White liberals never had to deal with the difficulties of minorities in getting a job, in the legal system, and in their own jobs. See https://en.wikipedia.org/wiki/Racial_wage_gap_in_the_United_States

As of 2009, the median weekly wage for African American and Hispanic workers was about 65 percent and 61 percent that of White workers, respectively. Maybe it's easier to be very liberal when life is good, and you don't have as many worries as minorities.
