So they are effectively not using the normal definition of meritocracy that people of same capability and will to work hard born in different classes can succeed at somewhat the same degree in intellectual professions, and instead talk about how people that are either unable or unwilling to do the work can’t compete with someone that does. How is this useful or meaningful? Why are we funding research like this using tax dollars, when an exact paper like this has already been written many times and already shown to be meaninlesss?
