At what point does society stop paying for the sins of their fathers?

I think the problem is a good chunk of American society is disenfranchised. The immigrants who come here, start businesses, and send their kids to college will be more successful than those who don't embrace the American way of life.

I think that as a society we will never be able to move fully forward until we can forgive the sins before us. We need to learn from them, remember them, but not dig up dead horses to beat them every time a problem relating to an issues comes up.

Certainly one point where "we stop paying for the sins of the fathers" is when we learn the lessons of history so we do not repeat them. This includes the obvious ban against civil rights violations in its obvious racist form but should also entail barring of any racist or sexist policies. You can not prove racism was wrong by enacting policies that reduces options and opportunities, marginalizes, or punishes one generation of a certain race in order to make up for past racial/gender crimes. This type of thinking is morally bankrupt and sets in perpetual motion a dangerous moral pendulum of racist policies favoring opposing groups from one generation to the next.
