This entire week I'm discussing CHEAP: The High Cost of Discount Culture with Atlantic colleague Megan McArdle on her fascinating and informative site. It seems that Megan and I both spent a portion of our younger years in menial jobs that required us to share bedrooms--and in Megan's case a bed--with strangers. Interestingly, this did not lead us to similar world views....so the discussion should be lively and possibly even enlightening. I look forward to your comments....
