The government knows that the protesters cannot stay on the streets for ever. There is an economic penalty for demonstrations: Students missing classes, employers and workers missing gainful employment, and so on. Even unemployed persons would find it uneconomical to be permanently mobilized. The government knows this and is counting on the traditional docility of Egyptians who have historically shown themselves averse to political violence. In the end, thinks the government, self-interest will drain the streets, and they are probably right. Which brings me back to the course I have advocated for the past ten days: The protestors must invade the presidential palace, at once. They must waist not a single minute more.
