Obviously a huge number of people died due to the Black Death but why didn't it leave a more lasting impression?

When i was taught about the black death in school we learned that people died and then we quickly jumped on towards the next event. The black death was just... there, somewhere in the middle ages. You can talk about a before and after the french revolution, a before and after Martin Luther, and a before and after the fall of Rome, but I've never heard someone talk about a before and after the Black Death. How can a plague that wikipedia says killed 30-60% of Europe's population not change the structure of societies? Half of the population have died, whole villages have been wiped out, and and there was no big push from any group to grab some more power in this vacuum that must have been?

If i look at the political climate today and imagine a plague that wipes out half the population i would think different (surviving) groups will try to seize as much power, land, property, wealth, etc. as possible. This would mean changes in laws and governments and even habits of ordinary people. Was there something like this that i don't know about or, if there wasn't, why didn't it happen?
