Root causes are often not as complicated as we imagine. For example, a lot of the problems on main-street come from single-minded focus on profits to the exclusion of the customer and employee. A lot of the frequent meltdowns of our economy come from rewarding those responsible for them with bonuses and bailouts, while the rest of us suffer the consequences.
The problems in Cairo, like the problems in inner cities, are fed by one root cause: politicians pander to those few identity groups that they can cobble together to win the next election, after which they switch allegiance to those groups that will contribute the most money to their next reelection campaign.
The two groups are not the same. Blacks, immigrants, inner-cities get all the lip-service because they are needed before the election for their votes. Then unions, lawyers, wall street, banks, corporations get all the regulating and lawmaking because their contributions are needed to get reelected.
Cairo can’t supply very many votes, and no campaign contributions at all. They might as well not exist.
