Does it make you feel bad?
Does it make you wish you could live that life style?
Does it make you try to live that lifestyle?
If you're poor and you watch shows that portray poor people:
Does it make you feel not so bad?
Do you accept what life has dealt you and learn to love it?
Personally I like watching stuff like It's Always Sunny, Flight of the Conchords, and The Young Ones, because it makes me more proud that I only have 3 pairs of jeans, shared a room my whole life, have a bathroom with no doorknob, have a non-functioning kitchen, and make stuff for people as gifts instead of buying things.
