Few ideas came to mind when I am facing this question as I think of it all the time..
1- All ministers should have MBA's from respected schools. (school names that WERE in the Ministry of Higher Education list 10 years ago.. and not added in the last few years)
2- All wikala and el wikala el mosa3ideen from all ministries should come from Private sector! and have at least 10 years experience in a close enough field. The maximum level a ministry person should get is modeer edara!
3- the only exception for number 2 is when the person has an MBA from FT Rankings of top 20 schools in the world.
i will come up with more later on.
