Your arguments on the thorny situation of the economic downturn of the country Nigeria is highly pathetic in all ramifications. Though, the dollar factors are part of the woes, yet the government and those of the business community could be held responsible for the inconveniences caused in the nation.
What the government of Nigeria would have done was to put certain measures on ground. The capital expenditures of the budget would have gotten a certain larger percentage to assist commercial farmers for massive production of goods and services, at best for exports. This shows that sufficient products would have saturated the domestic market to deal with artificial scarcity.
Again, a strong political will to direct the activities of a consumer protection society, a body created to control abnormal rises of prices of goods and services in the nation.
If these are done in Nigeria, the situation would be pleasant for all social classes.
