This unfortunately is human modus operandi. There isn't a single person, alive or dead, that has ever done differently. Though some of us are aware of that tendency and fight like hell against our own biases, in order to be better, when and wherever we can.

Politicians, on the other hand... play by a different set of rules, it seems.:-P On the one hand, it seems easier to just lie to the children then it does to explain whatever needs to be done, especially when they are cranky & dead set against learning (e.g., fluoridating water and iodizing salt = good?), while on the other, corrupt politicians also lie to line their own pockets and achieve their own goals, even if those may be detrimental to those they are supposed to be "serving". In either case, they lie:-|.
