Your thoughts are purely from the perspective of a person who can earn 7/hour, and which has Mcdonalds behind every corner. What about the countries where people work for less then 10$ per month (hard work), unemployment is high and it is difficult to find a job? In some cases users of faucets can maybe ( or maybe not), earn 1$ per day = 30$ per month - for you this is something like pocket money, but for some others this money means much more than anyone else can imagine.
that's a very good argument. it's too seldom considered on these issues.
if you come from a country with completely different conditions, the view is completely different.
if an average monthly income is partly below the level of a good lunch in another country, you can't assume the same sums here.
