R.A. Heinlein -

"Throughout history, poverty is the normal condition of man. Advances which permit this norm to be exceeded--here and there, now and then--are the work of an extremely small minority, frequently despised, often condemned, and almost always opposed by all right-thinking people. Whenever this tiny minority is kept from creating, or (as sometimes happens) is driven out of a society, the people then slip back into abject poverty. This is known as "bad luck."

On cognitive dissonance

When someone tries to use a strategy which is dictated by their ideology, and that strategy doesn't seem to work, then they are caught in something of a cognitive bind. If they acknowledge the failure of the strategy, then they would be forced to question their ideology. If questioning the ideology is unthinkable, then the only possible conclusion is that the strategy failed because it wasn't executed sufficiently well. They respond by turning up the power, rather than by considering alternatives. (This is sometimes referred to as "escalation of failure".) - Steven Den Beste
