so how many senator's sons do you know of in the military and a front line unit? have you read 'war is a racket'?
you think anything has changed?

nothing has changed...
who do you think will pay for 'space tourism'? who do you think will pay for nightclubs and bars in space? and who do you think will use them? why would the income gap be growing? how can the rich afford to go to space? what are 'war-time profits' and how are they related to today? all these questions and more... answered in tomorrow's show...
who's the duke of your local district? i dunno, look it up, he's probably in the phone book under the title 'sir', or 'honorable', or whatever the local tradition is... those types of nobles still exist.
but the real types of aristocrats you should be worried about are those who currently lead govts/companies... they're the same feudal dynasties from europe, which now own 90% of america... fundamentally, it's no different: you still have individuals/families who exert an excessive amount of control over local/state matters to benefit their families, at the expense of the 'peasants' (ie: rest of us).
instead of national imperialists though, they are now corporate imperialists... personal, capitalistic empires - instead of national militaristic ones (narcissism is usually involved, ie: entitled aristocrats). but almost all of them mix business with politics (sort of like fascists).
but that is just the beginning... when does it end? when you say it ends...
- when the peasant/slave state fails to serve, the aristocracy starves? - ghost in the shell
