Well, going at it from a newcomer's perspective, the fact that the opening narrative remarks on those "shortages of every kind" (Even shows two boys fighting for something with knives and a angry mob of people swarming a factory), and immediately outside of Sanctuary there's a gas station whose prices are $200 a gallon...yeah. I'd say a newcomer is going to get the idea that things weren't all sunshine and roses pre-war.
To be fair, if you keep scouring that laboratory and find the Director's terminal, the reasons for that mandatory overtime is explained. Basically, the bombs had already fallen and the only way the Director could get a military escort for them out of the city was if they had materials "vital to the war effort", ie what they were working on. He locked them up and forced them to work as a means to save them.
That probably has more to do with differences between the coasts. The Mojave certainly had plenty of Robots kicking around - it's possible the Northwestern Commonwealth simply had legislation that restricted robots. We know from the Fallout 1 intro that Mister Handy was being advertised and likely sold in the region, but given the general technical aptitude of the Core Region was higher then in the eastern wastelands, my guess is the various domestic robots were quickly cannibalized for their rare components by survivors eking out a living. Maybe the early Brotherhood rounded the majority up, before their dogma entrenched itself too much.
