The problem with putting a dollar number on it is it's devoid of context. Lunch from McDonald's is going to cost me $15 in the US, so $6 is not enough to live off of here. But the actual number is irrelevant. Is it enough to get food for the day or the week. How about housing? $6 doesn't sound like a lot, but if lunch is $0.50 and a roof over your head is $1.00 for the night, $6 goes a lot further!
