A bedrock belief of liberals is that most of humanity is too dumb to come in out of the rain without some nanny figure to tell them to. The thinking then suggests that the best form of government is one in which an elite cadre of exceptionally intelligent folks benignly show the rest of us what to do and where to go. All in our best interests of course.
Often enough, the voters go along with this and elect someone purporting to be smart enough to manage all our affairs. He or she seldom lives up to expectations, but the party simply says that the failed one simply didn’t try hard enough, and the next one will work out just fine.
Sure enough, the voters elect the next messiah, who works out about as well as the last one. If you think about this long enough you come to the inescapable conclusion that mankind is not ready for self-government, and that intervention by a passing band of benign aliens is our only hope.
