Cost of living around the world is increasing that's why having only one source of income or even 2 might not be even enough depending on where are you living. If you live in urban areas, you might be having a hard time budgeting because prices of commodities and necessities are more expensive than if you are living in rural areas where there is lesser expenses as well.
Does your friend don't have any emergency funds? Because if he only saved emergency funds then he will not experiencing what he is experiencing right now or at least in the next 3-6 months depending on how much did he saved. TBH, I don't know the reason why people don't have any emergency funds. Maybe one reason is their salary is just enough for their daily needs that's why they don't have enough money to save. Either way, not having an emergency funds will put you into trouble.
I hope that you're friend is fine, and help him as much as possible, but have a limit or else, you might find yourself having a hard time because of helping him. Saving money for at least 3-6 months just incase things like this will happen will save you. For sure, that's enough for a person to find a job that will support his needs unless he's lazy.
