During the rule of President Diouf from the early '80s to 2000, the government began to support a shift away from state involvement in the economy and towards more privatization in areas such as agriculture and textiles. Although this initiative continues to be supported by President Wade, the current government has run into issues with increasing numbers of unionized workers, thus hindering the attempt to implement a privatization policy.
The country has also faced some economic difficulties due to a steep population increase and unmonitored migration from rural areas into Dakar in the past 40 years. In light of the potential negative aftermath of such recent developments, Senegal's economy has more recently been largely aided by foreign assistance. In particular, the Millennium Challenger Corporation (United States aid initiative) has provided Senegal with $540 million in aid which will be put towards the creation of a new airport in Dakar and improving local roads and farmland. Therefore, despite the economic downturn in recent years, it appears that foreign aid will be of great help in getting the Senegal economy back on its feet.
