Though fantasy is to accompany real life story. And I didn't see fantasy in your narration. As for me it is reality and in Economic analysis, $1500 per/week is a huge amount of money that can solve the macro Economic deficiencies in a family of 5.
The macro Economic deficiencies are:
1. Poverty
2. Hunger
3. Squalor
4. Unemployment
5. Clothing etc.
And $1500 per/week can solve the above mentioned deficiencies. Although I am not from Philippine and I don't know their cost of living and the inflation rate but I still believe the amount can be utilized to some extent.
