Jumping to conclusions about one's status based on how many trinkets they were buried with is a dangerous exercise.<p>Plenty of victims of human sacrifice were buried with a plethora of artefacts. Conversely, many of the world's most powerful lie in very unremarkable graves.
Interesting, but not particularly surprising. I think a more interesting finding would be a culture where the remains of wives, mothers and other female relations of leaders and high-status individuals were not treated with some level of pomp and circumstance.
