The classic example is Shylock in the Merchant of Venice. The Jews had a racial stereotype of being moneylenders; that stereotype didn't evolve because of a racial disparity, it evolved because Christians generally didn't charge interest. So the moneylenders were non-Christian and that correlated with being a different race.
There is evidence of a slight bias where Asian migrants sacrifice more to set up their children's educational future. Policies that cheapen the impact of sacrifice will disproportionately affect them. It may not be explicitly racist, but the outcomes will likely be delectably different in different racial groups, to the net loss of the Asians.
