As you all know, Africans are nearly always portrayed as impoverished. While this is a reality for many Africans, there is an African middle class and even an upper class, though the latter is rarely seen in rural communities. Still, even members of the African middle class can find themselves with scarcely a dime in their pocket. That is because the notion of economic class here is not necessarily a function of how much money you possess at a given time. The Beninese have monetary habits that are largely dependent on their social practices, notably interdependency.
Beninese spending can be summed up this way: "spend it while it's hot". Savings are rare here because if you have an unexpected expense, you simply borrow money from a friend. Because of that, many Beninese are eager to spend their money while they have it rather than see their money whisked away by a friend in need. Less prudent Beninese spend their money on fancy clothes, beer, and other luxuries, while more prudent Beninese invest the money in a construction project, often a home. If you put your money in bricks and mortar, your friends and family cannot borrow it from you, yet you are still investing in your future.
To illustrate Beninese spending habits, I'll take the example of a teacher friend. As a teacher, he makes an amount of money that is luxurious in a village like Sonsoro. Yet he said that as soon as he gets his money, he goes on a spending frenzy, buying nice clothes and other luxuries, so that two weeks after his monthly payday, he is already down to his last $2, even during months when a bonus doubled his salary. Essentially, no matter how much money he received, he would still spend it all every month.
Some clever Beninese come up with systems that allow them to accumulate assets that can be liquidated when they need a lot of money for a big purchase. For instance, most of the summer's crops have been harvested by Christmas. The corn is stored in sacks to be sold, preferably in the spring when prices are highest. Twenty sacks of corn, for example, is enough to buy a motorcycle if the corn is sold when prices are good. However, some people who never have a dime in their pocket and want to celebrate the holidays with fancy clothes and expensive beverages will sell a sack of corn in December to afford their celebration. These sacks of corn only fetch half of what they would in the spring, so forward-thinking Beninese buy these cheap sacks of corn in December and wait to sell them for a handsome profit in the spring.
Another system to save money for large expenses is a tontine. One of my friends is in a tontine. Every market day (once every four days in Sonsoro), each woman deposits $4 with my friend, who acts as their treasurer. In all, she collects $40 (six participants pay at the normal rate, and two pay at a double rate of $8 each market day). After two market days, once my friend has collected $80, she gives the money to one of the women, who uses it to pay for a large purchase that she needed to save up for. Each woman gets a turn to receive the money until everyone has had their turn, then the tontine cycle starts again. The order in which each woman will get her share may change every cycle, giving a woman who knows she needs the money at a specific time the opportunity to request to be the beneficiary around that date. My friend's tontine has existed for at least eight years, and obviously the system requires a lot of trust. Members of the tontine are not chosen lightly.
As a Peace Corps Volunteer, the Beninese spending and borrowing system works against me. When a Beninese person needs to borrow money, they target wealthy friends, relatives, and even strangers, believing they can give most easily (hence the importance of hiding your wealth or spending your wealth). Because of my white skin, I am automatically considered to be wealthy, regardless of whether it is true. This means that I am expected to be a lender, but never a borrower. Furthermore, because I follow American habits of setting some of my money aside in savings for a rainy day, that means I am far more likely than a Beninese person to have money on hand to be borrowed. Also, since American values expect self-sufficiency, it is hard for a volunteer to accept the Beninese system of interdependency to the point of asking someone else for money. Hence, Peace Corps Volunteers generally have nothing to gain and everything to lose from this system.
While some Beninese hate being targeted as lenders, others do not mind because of the local expectation, particularly rooted in the Muslim faith, that all good deeds on this earth will be rewarded by God after death. Therefore, while some Beninese actively hide and spend their money to avoid lending, others are glad to share in anticipation of divine reward.
