Why Egypt Is Building a New Capital City

Spent 4 days in Cairo in November 2018.  Uninhabited apartment block buildings everywhere, most without glass in the windows.  It was explained to me that purchasers/lessees were expected to buy the glass and appliances, etc. themselves.  As far as I could see, then, many buildings had barely 50% occupancy.  I don't, therefore, see the whole "housing shortage" issue.  It looks like corrupt builders have been able to secure permissions with no oversight or reference to any kind of zoning or other planning regs. and have built willy-nilly all over the city.  The massive grinding poverty in which the vast majority of the population lives makes such spaces unattainable and the shoddy construction means the middle classes don't want them.  So much easier for elites to head out to the desert, build their own utopia, and let Cairo go to the starving dogs, cats, donkeys, people, and oblivious tourists.  Nothing on the images you provide shows where the slaves on whose backs most of this will run are to live.  Also, who is paying for all this?  Has Egypt become progressive and gone for a tax the rich self-financing scheme or are the poor and middles classes shouldering a deeply unfair tax burden while the corrupt government goes heavily in debt to "whom"????  Reminds me of Greece just after joining the EU/euro.  The generals and their cronies made out like bandits on all the loans and now ordinary Greeks have been suffering for 12 years and will keep on suffering for another decade at least.  The average citizen of Cairo or rural Egypt will never see inside any of those facilities or benefit in the least from "the tallest building in Africa".
