Budgeting is good, but that would never solve the problem, in cases of inflation your budget will be disorganized because of price flactiation,
But while people keep talking about budget I think it's best to work on increase your source of income instead, use that money to create more money, sacrifice clothes, expensive and unnecessary items for knowledge of skills and capital, and that's why the call it financial freedom, what does budget in this level have to do with someone that is wealthy
You are correct, instead of focusing more on budgeting as a low income earner, what you should do or focus on is how to increase your income.
As a low income earner budgeting will never make you live comfortably because emergency will come up and you will use the money you have budgeted for a particular thing for it.
Budgeting is meant for those who are rich or high income earners to a large extent.
I am not saying that as a low income earner you should not budget, you need to budget because it will actually help you but your focus should not be on that your focus should be on making sure you increase your source of income.
