I would say the show does well to explain class welfare for the elite intellectuals. We need rocket scientists....but the truth is....ninety-nine percent of them aren’t really needed much. So we employ them at odd jobs, pay them what they think they are worth, and just grin over projects that have no value.
I won’t dump on Big Bang Theory....it is a well written script and they have done some five star episodes (the comet-passing episode with the guys out in the foothills was a classic).
Everything came easy for them so they were able to loaf their way through school. Anything hard was "not fun" unless they could make a game of it.
Occasionally they would come up with something brilliant but as far as performance they never would match the steady churn of workable ideas their less flashy co-workers produced.
Now I have to say that not all of them were like that. There were an equal number that were both brilliant and hardworking but I don't think they would have made for interesting TV.
