Archeologists could study our society without digging. All they would have to do is go to yard sales.
One could find out what books were being read, what clothes were worn, what kitchen gadgets were used, what toys filled our closets, what decore we used, what baby equipment was essential, what movies and music was watched and listened to, and bizarre items we collected, all so vital to our lives until no longer wanted. One man's trash...Now why wouldn't the giant brass crab no longer be found desirable for the living room's ambiance? What about the desktop steer horn set: why sell it? What made the O.J. Simpson magazine from the '70's lose its appeal? Why did the teddy bear matching sweaters no longer feel fashionable to grown ups? Don't they know that naked Barbie dolls never go out of style? Why did I fill my car with other peoples rejects and give them my money? Maybe it's better left to psychiatrics rather than archeologists.
"Do not lay up for yourselves treasures upon earth, where moth and rust destroy, and where thieves break in and steal. But lay up for yourselves treasures in heaven, where neither moth nor rust destroys, and where thieves do not break in or steal; for where your treasure is, there will be your heart also." Matthew 6:19-21
Early Presidents of the United States came home financially worse off than when they filled their office. Thomas Jefferson was so poor and in debt that even after selling his favorite possessions, his wonderful library to become the Library of Congress (the first library was burned by the British in the Revolutionary War), his relatives still had to sell everything when he died, all his land and earthly possessions and all his slaves (some of whom were his own relations by his slave wife Sally Hemings). It was a circus for gawkers and opportunists. Now that was a sad yard sale!
