That's true. I'm living in a third world country and life here is really difficult if you're not from a middle class or rich family. The minimum wage salary is not enough to sustain the needs of a family of 5 or more, it's already hard to budget due to the increase of almost everything unless other family members are also working.
So to survive, you really need to prioritize the needs before the wants. I think if you already experience hardship, you're already aware of what you should do that can make you become wiser when it comes to managing your money. In addition it is advisable to not rely on your main job because as we always said, having an extra income is much better because this can maximize your earnings. This way you can provide for what your family needs and can somehow save.
I also live in a third world country where inflation is over 50% and the government have not increased the minimum wage. This has led to high rate of crime and suicide in my country. What me and my family did was to cut down on our expenses. We observed that school fees was eating up most of our finance and if we don't reduce it, we might starve. My partner is a qualified teacher, so we decided to get the necessary approval and started homeschooling the children. And it worked perfectly because the children were able to pass all the standardized examination last year. We also reduced our spending on clothing. We ensured that we bought quality clothing that are durable so that we don't keep spending consistently on wears. Our family also had to move from our neighborhood to a cheaper house somewhere else. We also had to learn to eat locally produced food and reduced our spending on some expensive imported meals. These changes were very painful, but we had to make these sacrifice so that we can survive in this perilous times.
