On the topic of race, why doesn’t the Declaration of Independence and the Constitution of the United States uphold justice and equity for all groups of people?

"Throughout history, most people have been treated unequally by their rulers. Unless one were born into a privileged family or tribe, there was little access to the precious resources that are taken for granted in a prosperous society—things like meat, well-defended shelter, and education. In many cases people might be enslaved, or something close to it. People were treated unequally, both so that the powerful could have more comfort, and because rulers believed most people couldn’t be trusted to make decisions about how society should operate. As we have seen, the Founders declared that no one has a right to rule others simply because of the family into which he’s born. Instead, they believed that everyone is born with certain rights and that the law should equally protect people’s freedoms and property."
