Virtually all of Saudi Arabia's food is imported, swapped for oil. Anyone<br>have an idea of how many that part of the world could support without food<br>imports?</blockquote><div><br>It depends upon whether they invested in desalination plants to grow fresh water crops or invested in solar ponds to grow fish, shrimp, etc. in salt water. It isn't as if they *lack* sufficient sunlight to feed themselves. Indeed it is one of the world's richest countries in this respect. See [1].
<br><br>I suspect that the reason there is so much unemployment is that the government simply has not adopted policies reflective of dealing with the situation when the oil runs out. It isn't like they couldn't afford to build the plants or the ponds -- but I think the culture is set up such that that work would be done by workers imported from poorer countries.
