The following history might be insightful to readers. This was written in 1995--only 20 years after the country's first 5-year plan.
"In 1975, Oman initiated the first of four five-year plans that have depended to a large extent on the price and production level of petroleum. At present, since Oman is finding new reserves at almost the same rate that old ones are being depleted, the government's goal is to maintain the present production level of 800,000 barrels per day for the rest of this century.
The extraordinary building and beautification program in Oman's capital and its suburbs was made possible largely by the increase in the price of oil in the late 1970s. New ministries, shopping malls and residential villas sparkle white in the sun in an almost continuous strip from Bustan, east of Muscat, to Seeb, the site of a brand new international airport more than 20 miles to the west. At present, with the price of oil stagnant and delineated in a sinking dollar, Oman has less money to spend on such beautification, but it nevertheless has undertaken major regional expansion and beautification in towns throughout the country.
Having accomplished most of its infrastructure-building goals in its first quarter century, Oman's government will concentrate in its upcoming five-year plan on 'Omanization,' inducing the private sector as well as the government to find jobs for the growing annual number of graduates from Oman's schools. It also is focusing on environmental protection, on encouraging Omanis to save more of their incomes and thereby reduce the need for foreign investment, on freshwater conservation and production, and on dealing with its extremely high birthrate through education."
In the last two decades the large population growth has been called into question and their have been some major social and economic debacles--including issues of corruption. In short, at times Oman has stumbled a bit over the last two decades but its population growth is slowing too. This means responsibility for family planning is being made at the individual level and more citizens want responsible growth and planning in all aspects of their social and economic lives.
