Good try Sisi, but the term upper crust goes back much further than that. In the 1300's, they did not usually use plates or platters to eat on. They were reserved for serving. People would eat on slices of large round bread (called Trenchers sp?). Well you can imagine how soggy and messy these things became after numerous courses, leaking all over the table and the guests. The nobility were always offered the first (or top slice) since it was covered in crust making for a less messy edible plate.
