In my experience people are not so much stupid than lazy.... It is difficult for me not being stupid more than half the times each day... That task ask for thinking, reading, studying, be silent(very difficult for me).... I hope I am not totally stupid... I think I am not totally stupid because being stupid is a choice not a genetic affliction... and i try to read and think a lot …. Perhaps not enough? Who want to think? And more important: who want to meditate about his own thinking and acts and choices? Intelligence begins after the meditation then, not solely after some thinking.... Thinking is not enough.... :)
One by one the individual composing the mass are not stupid they are lazy...The mass is a mass....Inert and instinctual like a beast or robotic like an army....Political direction is there to drive the mass to synchronized action instead of erupting instinctual acts...
