There is nothing unusual about a local segment of elites benefiting from imperialist conquest. Their collaboration with the vanquishing power has rewards. Neoliberalism does create millionaires, even billionaires in the societies where it is imposed; yes obviously, at the expense of the population. The local beneficiaries are always those who already had privilege and power within the society; the most organized and influential business and intellectual classes; and they will consolidate their privilege even more as agents of the imperial power structure. This is standard.
In a place like Egypt, or Pinochet’s Chile, those beneficiaries are the army, land owners and a handful of industrialists. In British India, it was the Brahmins. In most of Latin America, it was always those of European descent. It is an absolutely consistent phenomenon.
The local population will tend to focus their hostility against the elites whom they have always known, and whose corruption they are familiar with, and whose oppression they have dealt with for years. When they see this faction enriching themselves even more, and see their abuses increasing, they make the mistake of thinking that they are actually the dominant authority, when in fact, they are simply the managing authority for the dominant power.
There is nothing unique about any of this.
