What exactly does "worth" mean in this context? If it's an abstract idea of right to life, liberty and the pursuit of happiness and the idea that an existence should be respected, then yes, all persons are of worth. But if "worth" is meant in terms of the capacity of an individual to increase my (or your or company X's) share of goods and services than manifestly all people are not of equal worth. This isn't society discriminating, it's reality. And intelligence is only one (albeit important) component of this. "Worth" in an economic sense isn't fixed. People can (and do) make themselves worth more. But probably they do it less if they are raised with an idea that worth doesn't have anything to do with effort.
