The first thing to know about Yuppies is that they have no national or community allegiance; therefore they are International Capitalists who enjoy exploiting the labor of third-world nations for their own private profits. Usually, Yuppies will live in "secured" buildings or a precious "gated community" surrounded by other Yuppies who fear working class retaliation. Yuppies are the bane of all racial minorities and actual Americans because they undermine, subvert and sneer at anyone who does not make $250k a year. Certain Yuppies want so badly the false appearance of being "down" or "hardcore" -- used as a sneaky trick to hide their obviously large paychecks (pejoratively known as a "urban 'hipster' "). But, when push comes to shove they would just call their precious police or cry like little bitches.
Generally speaking, Yuppies love to appear cultured and have roots, when in reality they are just conformist shills willing to do anything and bend over at any command.
Bob: Jim! We need to hire some more compliant Yuppies who will let us use them for our evil goals.
Jim: Yes master. I will see that a new batch are brought in right away, your magnificence.
Bob: Excellent workplace compliance Jim -- sure to reward you many dollars.
Jim: Pleasing my master is the only holy financial goal.
