Read this, and think about the last part really hard.

In a country which is moving downhill, the fraction of stupid people is still equal to å; however in the remaining population one notices among those in power an alarming proliferation of the bandits with overtones of stupidity (sub-area B1 of quadrant B in figure 3) and among those not in power an equally alarming growth in the number of helpless individuals (area H in basic graph, fig.1). Such change in the composition of the non-stupid population inevitably strengthens the destructive power of the å fraction and makes decline a certainty. And the country goes to Hell.
