Hopefully anyone who is a member of this forum and is ONLY making minimum wage in a place like Bangladesh and/or any other country with similar kinds of low level wages, these people should be working towards increasing their wages rather than merely making minimum wage...
easier said than done. Bangladesh is the 8th most populated country in the whole world. in a place like this the competition is so high and the opportunity is so low that you should be happy that you are making a minimum wage. but not all people are only making the minimum wage, there are people whose daily expenses is more than minimum wage earned by people.
there are some side hustles that you can do in order to increase your wages but finding a proper job and keep doing the side hustles is quite a bit hard in here.
If there are sides hustle that can add more income, then @JayJuanGee is right. Some people are already working hard beyond the minimum wage, so anyone who crave for a better future should endeavour to explore other areas that can earn them money.
Fortunately, I know a lot of hardworking people from Bangladesh that are doing multiple freelancing jobs to make ends meet. This is not perculiar to Bangladesh, many people from low income countries strive to earn more money to be able to meet their needs.
