<human>:  Where does the concept of equal opportunity come from?
<bot>: The concept of equal opportunity is based on the idea that everyone should have the same chance to succeed. It is a fundamental principle of the United States Constitution. The Equal Protection Clause of the 14th Amendment states that “No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.”
