Here’s how Wall Street wants you to celebrate the holidays: spend, spend, spend. They want you to rush out and shop until your credit cards are smokin’ hot. They want the affection you feel for your loved ones to translate into stuff — more sweaters, more iGadgets, more games and toys. They want your money to trickle up, not only through your purchases, but also through the credit card interest you’ll be paying until the next holiday season. Who cares if you protest as long as you buy more shit?
