The first argument that I hear is that the salaries are so much higher in Canada, the US, Europe.... well, they are but so are the costs of living. So they basically cancel out. The ideal thing is to be paid by Europeans to live in Egypt, but that's not so easy to manage.
Life in Egypt is not as risk-free as many in Europe and North America would like, a fact for which I am forever grateful. In a "civilized" country with lots of liability insurance, I wouldn't be able to have friends of mine ride my horses unless I was insured up to the eyeballs. Driving anywhere here is an adventure, but once you get the hang of it, no problem. You DO and SHOULD think a million times before you attempt drunk driving in Egypt, however.
It's very hard for people to starve in Egypt. Any fruit seller has a box on the sidewalk in which they place fruits and vegetables that are below standard for the poor who need food. Real food is cheap. You have to wash it and clean it and prepare it for cooking and then have to cook it....Horrors! But it's cheap and good and fresh. Shopping in the US is a nightmare for me because the grocery stores are full of prepared foods that aren't particularly good for you, items for cleaning that are immediately disposed of (what happened to the good old wet rag?), extraordinary quantities of personal hygiene products, and cheap junk food. Coca Cola is cheaper than juice. Great. No wonder the US has major health problems.
Egypt has sunshine about 360 days a year, unless you live on the North Coast, where it actually rains in the winter. I'm outdoors every day. Yes, it's dusty, but I daresay so is Tucson. I can put up with some dust.
One of the main criticisms of Cairo especially is that it is "dirty". Well, yes, it is. Some of that dirt is deposited by its loving neighbour, the Sahara Desert. Some of the dirt is the result of the way-too-many human inhabitants of the city, about 20 million of them. Not too easy to clean up after so many, as I'm sure that London, New York, and Los Angeles could testify.
I believe that too many people expect to visit foreign countries the same way that they visit Disneyland. They expect surgical cleanliness, and neurotic orderliness. Guess what? Most of the world, including huge chunks of the US, isn't like that. Egypt is real. It has problems, but it also has an extraordinary spirit and joy in living. Urban life is doing its best to beat it out of everyone in the world, but so far it hasn't won in Egypt.
Why live in Egypt? I've lived in San Diego, near Santa Barbara, San Francisco, Vancouver BC, Toronto, and visited more citiies in the US and Canada than I care to remember, and I prefer to live in the countryside outside of Cairo, thank you. You couldn't pay me enough to move back.
