How can a family man who earns 50k with 3 kids and also paying for rent feeds and many more, how can he with stand this economy pressure where there is no stability no mouthwatering salaries at all. This days we wake up and pray things should get better but it's like our country does not accept prayers everyday increments.
From your local board engagement, it seems you are a Nigerian, and the 50k you mean, I guess you are referring to Nigerian local currency, which should be worth $32 if converted to the current rate based on my research.
If the economic situation in Nigeria is so bad and the inflation rate is so high, then it's very important for you to cut down on your budget and relocate to a less expensive apartment or a location where the cost of living is less expensive.
I remember, while I was young and growing up with my grandmother in a village, that she had a farm where she cultivated some vegetables, maize, potatoes, and some other crops that lasted no longer than 6 months before they were due for harvest. With such engagement in the cultivation of those vegetables, it helped her not to be buying everything in the market; at least she could easily get some vegetables from the farm, which helped to reduce costs for her. So, there are some locations where you will live and you can manage your finances very well, but if you are living in a city where the cost of living is very high, probably because traders travel far to purchase goods for their businesses, the price of things will definitely be higher than when you are living in a local place where you can get some things easily at a low cost.
So, to help you fit it, relocate to a less expensive apartment, cut down on costs for your family, and always make a budget for your spending.
