> Do you have any idea how juvenile and tasteless you look in cheap jeans and sneakers? Do you realize how much dramatically better you look with proper shoes and well cut wool pants? To give up that advantage just indicates idiocy to me.

I won't deny that dressing up is a social advantage, but sometimes people care about some things more than strictly getting ahead. It's entirely possible that an individual could place more value on being comforatble than on getting that raise or promotion.
