Egypt's per capita income grew over 20x from 1965 to 2015. And consider the population increase that happened over the same period. The overall GDP (constant US dollars) grew from $5B to around $335B.
Egypt is the cradle of civilization. The Nile hasn't gone anywhere. As soon as they get their heads out their asses and let farmers own farms rather than military cronies, they'll be able to feed themselves again.
No, see, "cradle of civilization" is exactly about resource constraints. They have water and sunlight and good soil, and those are the resources needed for agriculture. People living in Egypt and running short on grain is a temporary condition that condemns their government not a permanent one that condemns their land.
Don't give me that "They can't do it" nonsense.
