Individual rights are universal — they belong to each individual equally by their nature as a rational being.
Though individuals differ in their ability to reason, this does not change the fact that reason is a human being’s distinctive means of survival.
Take, for example, the right to property: all individuals have the equal right to property honestly acquired, whether one is Queen Elizabeth or a street-sweeper. The right to property does not mean one will own property, but only that when one has honestly acquired property (through production or trade), that property is one’s property not by permission, but by inalienable right. The right to property does not mean all individuals will have an equal amount to property, only they will have the equal right their property.
