You see in Egypt the problem comes from the politicians and they arise from the culture.
Unfortunately Egypt has a culture of kleptocracy, corruption and favouritism.
When he was President, Hosni Mubarak enriched himself to the tune of US$42 billion. This is scandalous but hardly unexpected, because politicians in absolute power will both use violence to retain power and will be thieving bastards one and all. Yet this is what politics does. By granting unlimited power to people elected or otherwise, they do violence to others, they collect money through violence and can use it to corrupt, and can be corrupted to change laws, grant contracts and the like.
It is what politics can do and does, and liberal democracy doesn't contain it, culture does. In the US, politics is corrupted because people seek favours from politicians in the forms of money or privileges granted by the state. However, there is an independent judiciary and free press, so there are institutions in place that can contain this.
In Egypt this doesn't exist. It is stuck between the kleptocratic authoritarian culture of the army, which has deep roots in business and the economy well beyond what should be its core role.
However, Islam also has deep roots that mean that a significant plurality of Egyptians are quite happy for the state and religion to be as one, meaning non-Muslims in Egypt face serious risks of oppression and discrimination by the state.
So when foreign observers call for free and fair elections, that's all very well, but what is the reason for this? What do they want for Egyptians?
