let’s look at the different ways to configure a society, in engineering terms.

what the new class seek to do, is create a highly stratified structure with little true connectivity between the layers(i.e. classes). it would cut across national boundaries, which would be nominal at best.

this design would be very suceptible to shearing forces, and would be highly inefficient since there is absolutely no motivation to produce extra, once the overclass had theirs.

a much stronger and more stable design, creates myriad and comples webs of connections, without clear boundaries. the people at all levels (except again, at the top) have every motivation and opportunity to produce as much as is profitable.
