According to Goldstein, who are the new aristocracy?
According to Goldstein, the rise of totalitarian states like Ingsoc brought with it the rise of a new kind of aristocracy. This was an aristocracy that was focused mainly on getting power for itself. It was focused on using the power of the state for (more than any other goal) crushing any opposition.
According to Goldstein, this new aristocracy was made up of people who could either run the government or influence it. It was made up of people like technicians (who could run stuff) or union organizers (who knew how to influence government) or publicity experts (who knew how to put out propaganda). All of these were types of people who could build a new and totalitarian system of government that would dominate the new states.
Here is a quote that illustrates this idea:
The new aristocracy was made up for the most part of bureaucrats, scientists, technicians, trade-union organizers, publicity experts, sociologists, teachers, journalists, and professional politicians. These people, whose origins lay in the salaried middle class and the upper grades of the working class, had been shaped and brought together by the barren world of monopoly industry and centralized government. As compared with their opposite numbers in past ages, they were less avaricious, less tempted by luxury, hungrier for pure power, and, above all, more conscious of what they were doing and more intent on crushing opposition.
