No? Chevron has over 2000 employees out there and is currently hiring.
Nigeria is classified as an emerging market, and is rapidly approaching middle income status, with its abundant supply of resources, well-developed financial, legal, communications, transport sectors and stock exchange (the Nigerian Stock Exchange), which is the second largest in Africa. Nigeria is ranked 37th in the world in terms of GDP (PPP) as of 2007. Nigeria is the United States’ largest trading partner in sub-Saharan Africa and supplies a fifth of its oil (11% of oil imports). It has the seventh-largest trade surplus with the U.S. of any country worldwide. Nigeria is currently the 50th-largest export market for U.S. goods and the 14th-largest exporter of goods to the U.S. The United States is the country’s largest foreign investor. 
The bulk of economic activity is centred in 4 main cities: Lagos, Kaduna, Port Harcourt, and Abuja. Beyond these three economic centres, development is marginal and poverty is still prevalent despite government efforts.
While economic development had been hindered by the years of military rule, corruption, and mismanagement, the restoration of democracy and subsequent economic reforms have successfully put Nigeria back on more secure economic footing. According to the Economist Intelligence Unit and the World Bank, Nigerian GDP at purchasing power parity has nearly doubled from $170.7 billion in 2005 to 292.6 billion in 2007. The GDP per head has jumped from $692 per person in 2006 to $1,754 per person in 2007.
During the oil boom of the 1970s, Nigeria accumulated a significant foreign debt to finance major infrastructural investments. Many of the projects financed by these debts were inefficient, bedeviled by corruption, or failed to live up to expectations. When oil prices collapsed during the oil glut of the 1980s, Nigeria was unable to maintain its loan obligations and eventually defaulted on its principal debt repayments, limiting repayment to the interest portion of the loans. Arrears and penalty interest accumulated on the unpaid principal and increased the size of the debt. However, after a long campaign by the Nigeria authorities, in October 2005 Nigeria and its Paris Club creditors reached an agreement in which Nigeria repurchased its debt at a discount of approximately 60%. Nigeria used part of its oil profits to pay the residual 40%, freeing up at least $1.15 billion annually for poverty reduction programmes. As of April 2006, Nigeria became the first African Country to fully pay off its debt (estimated $30 billion) owed to the Paris Club.
Nigeria is the 12th largest producer of petroleum in the world and the 8th largest exporter, and has the 10th largest proven reserves. (The country joined OPEC in 1971). Petroleum plays a large role in the Nigerian economy, accounting for 40% of GDP and 80% of Government earnings. However, agitation for better resource control in the Niger Delta, its main oil producing region, has led to disruptions in oil production and currently prevents the country from exporting at 100% capacity.
Nigeria has one of the fastest growing telecommunications markets in the world, major emerging market operators (like MTN, Etisalat, Zain and Globacom) basing their largest and most profitable centres in the country. The government has recently begun expanding this infrastructure to space based communications.
The country has a highly developed financial services sector, with a mix of local and international banks, asset management companies, brokerage houses, insurance companies and brokers, private equity funds and investment banks. Many home grown firms have expanded across the region and into Europe, Asia and North America becoming multinationals in their own right.
Nigeria also has a wide array of underexploited mineral resources which include natural gas, coal, bauxite, tantalite, gold, tin, iron ore, limestone, niobium, lead and zinc. Despite huge deposits of these natural resources, the mining industry in Nigeria is still in it infancy.
Agriculture used to be the principal foreign exchange earner of Nigeria. At one time, Nigeria was the world’s largest exporter of groundnuts, cocoa, and palm oil and a significant producer of coconuts, citrus fruits, maize, pearl millet, cassava, yams and sugar cane. About 60% of Nigerians work in the agricultural sector, and Nigeria has vast areas of underutilised arable land. Perhaps, one of the most daunting ramifications of the discovery of oil was the decline of agricultural sector. So extensive was the neglect that Nigeria, which was a net food exporter in the 1960s and grew 98% of his own food, now imports much of the same cash crops it was formerly famous for exporting.
It also has a booming manufacturing industry which includes leather and textiles (centred Kano, Abeokuta, Onitsha, and Lagos), car manufacturing (for the French car manufacturer Peugeot as well as for the English truck manufacturer Bedford, now a subsidiary of General Motors), t-shirts, plastics and processed food.*
Note that the term “corruption” occurs over and over as a reason why Nigeria isn’t doing as well as would be expected. That’s their own damn fault.
