The key problem for Egypt is that the army refuses to accept any democratic oversight. Bear in mind that the army controls half the economy. In Eastern Europe the solution to problem of an economy nominally run by the state but in fact controlled by a nomenklatura was privatization. I don't believe that was the best solution but it was one that made democracy possible. The alternative is to establish genuine democratic oversight over such an economy. However, to simply leave such a nomenklatura in control means that the dictatorship continues even if it may be disguised by a veneer of democratic trappings.
The recent coup makes the position of that nomeklatura impregnable.
My guess of half the economy was way out. 10-15% would be closer. However the army pays no tax and can ignore the red tape that private industry complains about. For such a privileged body to be outside democratic accountability is incompatible with democracy.
