Oman's socio-economic structure is described as being hyper-centralized rentier welfare state. The largest 10 percent of corporations in Oman are the employers of almost 80 percent of Omani nationals in the private sector. Half of the private sector jobs are classified as elementary. One third of employed Omanis are in the private sector, while the remaining majority are in the public sector. A hyper-centralized structure produces a monopoly-like economy, which hinders having a healthy competitive environment between businesses.
