Years ago I had read about elaborate road construction in Oman. Developing countries with few paved roads don't require much construction to show a large increase in roads. There was only one school in the entire country. This was a land of Bedouin nomads, tough desert-survivor warriors. Hospitals and medical care equal to or surpassing what we have in North America.
Medical staff is paid more than in Canada.
Sultan Oaboos Bin Said combed the world and hired the best. Oman is still pumping 900,000 barrels of oil a day, but the Omanis did something worthwhile with their money over the past 27 years. Oil now accounts for only 40 percent of their income. Back to the Lost City of Ubar. With 3-D radar finally able to penetrate dry sand, much more of the world is now viewable.
