Yeah, yuppies as we think of them are pretty much extinct now. Their closest living descendants are the finance bros who drink at Midtown East bars.
Yeah. The biggest thing about yuppies was their overwhelming absorption with what other people thought of them. Needing to impress people and cultivate image. The truly wealthy assholes don't give a freak what you think of them. That's the difference. They have an utter disregard for everyone who can't do something for them, and they excrement on those people mercilessly with no regard for humanity or an ounce of empathy. The worst are basically sadists who can act in the open and with impunity.
Anyway, yeah, I don't see why anyone would call Tommy a yuppie.
