The worst thing for any country is when people sit idle. If there is an economic depression, and unskilled people lose jobs - then put them to work building roads! Nigeria has cement, roads can be built with interlocking stones. Use the depression to build roads everywhere.

In addition - there should be a strict policy - no idle land! Every land that is not farmed should pay a fine. Let everyone labour on farms. The excess can be exported or processed.

Those who have university education should teach. Introduced advanced afternoon classes via video and ask all those people to teach. All the village kids should be studying all the time.

Force productivity by creating local economic activity - force houses to be painted, make people keep gutters clean, plant trees, beautify, etc. Regulation and forcing particular activities stimulates an economy, as people either have to work or hire to work for them.

Create an import ban schedule for particular things, and import the machines for them instead. E.g easy plastics, leatherware and so on.

Allow unlimited, duty free import of cars and all mobility devices. When people move, it stimulates an economy. Forbid the banning of motorbikes. Bikes are efficient drivers of an economy.

Force the price of data down so that more people go online, learn how to do things and also find global opportunities. Mass import millions of smart-phones and sell at cost price to traders.
