The DC Wasteland looked pretty dead to me, if you meant anything besides Super Mutants, Rad Scorpions, and Raiders.
Girdershade was having raider problems. Ronald has killed two raiders at Girdershade.
Canterbury Commons was having a serious robot/ant problem.
The people of Arefu were afraid to come out of their homes.
Grayditch was wiped out by Fire Ants.
Megaton, Rivet City, Tenpenny Tower, and Underworld are some of the best fortified settlements in the DC Wasteland and there were still major problems.
Rivet City was still having serious clean water supply issues.
Tenpenny Tower was about to have a serious ghoul problem.
And the caravan trade route was barely getting by.
Now in the Mojave, it was a different setup.
The Mojave was in the process of recovering till the NCR/Legion war started and never stopped.
All the unrest was mostly due to the ongoing war.
Certainly without the war the Powder Gangers would never been allowed to revolt or been allowed to continue.
The Fiends were secretly being armed by the Legion.
And of course there was the direct confrontations between the NCR and the Legion.
But otherwise there was plenty of clean water and power if you knew where to look for it.
They were even repairing the railroad between New Vegas and the NCR.
I will say that Obsidian did a better job in Fallout New Vegas with the people's attitudes/settlement atmosphere, but they were building on what Bethesda had already created.
