However, it is also true that non-Arab provinces such as Kohgiluyeh and Boyer-Ahmad Province, Sistan and Baluchestan Province, and neighboring Īlām Province also suffer high levels of poverty, indicating that government policy is not disadvantaging Arabs alone but other regions, including some with large ethnically Persian populations. Furthermore, most commentators agree that Iran's state-controlled and highly subsidized economy is the main reason behind the inability of the Iranian government to generate economic growth and welfare at ground levels in all cities across the nation, rather than a state ethnic policy targeted specifically at Arabs; Iran is ranked 156th on The Heritage Foundation's 2006 Index of Economic Freedom.
