"Emily" the most piglike people who dress like slobs I've ever known are RICH people. Rich white people which Susan mentions in detail. Then other rich whites do wear the logo shirts she mentions -- in detail. People dressing down at this theater event have NOTHING to do with people whose incomes prevent them from purchasing expensive designer clothing.
I'm a leftist as you clearly are NOT. Susan is talking about having respect for others and the community and the theater performers. NOT about "people have to wear torn jeans because they can afford nothing else."
Quit it and get a life, and while you're at it, grow up. Susan's talking about a respect for others which seems to be fading or totally gone. Primarily amongst upper middle class rich whites!
