The ancestors of short people, obese people, etc. weren't enslaved, forbidden to read, sent to second rate "schools", not given the right to vote, and weren't forbidden to work.
That's why there's less of an effort to make up for anything our society may have done to them.
We did really bad things until very recently and there should be an effort to make up for them. Removing most discrimination from society and education was a great start but there's still more work to be done. There are deep fractures in culture that need to be fixed.
It's very easy to forget how bad some of the things our country did were because most of us weren't alive then to remember it. So, it's very easy to downplay the effect of centuries of enslavement and another century of Jim Crow. Or, in the case of women, the effect of centuries of being denied basic rights such as voting, working, and being allowed to go to school.
There's just no way you do those things up to 1965 and expect all the problems they caused to have been fixed by 2017.
