I periodically see people talking about the "positive" effects of the bubonic plague in Europe: increased social mobility and economic equality, sometimes with a little too much enthusiasm.
Is a similar phenomena observable in Asia from the plague, or in any location from any similar pandemic? Is there any evidence for this around the Justinian plague? What other sociological effects can be seen after a pandemic?
Before asking whether the Black Death had an impact on social mobility in "Asia and other non-European locations", we really need to ask if the pandemic actually struck Asia and other non-European locations.
The evidence is meagre (telling in itself, I think), but there is good reason to think that in fact the pandemic hit only Europe, the Middle East and the far western portions of the Asiatic steppe, as I discussed in some detail in this earlier answer:
Why can't I find very much information about the 14th Century black death in Asia?
Others may be in a better position to comment on the Plague of Justinian, but I'd be surprised in sufficient evidence survives from such an early period to allow much detailed commentary on the social impacts of the first great pandemic.
