Straight: Alice lives in a tough neighborhood with her boyfriend Bob. She dresses in impressive-sounding fake labels (and her outfits tend to leave little to the imagination). She has a fake tan, and opted not to go to college (and may not have even graduated high school). Bob bought her a knock-off purse that allegedly Fell Off the Back of a Truck.
Exaggerated: Alice lives with Bob, her boyfriend of the month and already has five illegitimate children at the age of 23, by five different men. She is unemployed, instead living on welfare checks (and spending the majority of that money on things like fake designer clothes and/or recreational drugs). And she dropped out of high school (maybe as a result of her first Teen Pregnancy, maybe for another reason). Her lack of education is very evident in the way she speaks.
Downplayed: Alice has picked up a few bad habits and norms from living in a tough neighborhood. Nothing some effort (and maybe moving) could cure.
Justified: Life's nasty for Alice. The result isn't nice.
Alice is poor, but she is articulate in her speech and well-educated. She might even be an Almighty Janitor type.
Invoked: Alice becomes pregnant at age 16 and her ultra-religious parents kick her out of the house. She qualifies for government assistance, and so gets a place to live downtown (but it's not in a very nice area). She finds she has no time to finish school, between taking care of her baby and working at the local burger joint, so education or other self-improvement takes a backseat (and because of her young age, she may be lacking in the emotional maturity needed to set her priorities straight).
Defied: Alice either gets a GED or finds a way to complete High School and at least go to community college or trade school (maybe even four-year college), and works hard to make a better life for herself and her child (see "Subverted"). She puts her child's interests and long-term well-being ahead of short-term pleasure for herself.
