This is not a solution i can rely on. There is economic hardship and the price of goods and services have increased very much. Using $1.90 per day cannot be possible in this present condition because no services can go below $0.7 unless it is a very poor service. In many countries the money can be a lot to some persons but trust me if you check how much to get just breakfast then talk more about lunch and dinner you will get to understand that the $1.90 you estimated per day can only afford breakfast. That is the main reason why you see most people care about taking breakfast and dinners only. Lunch is rarely taken so as to save cost.

Don't worry OP when we see the right solution it will be obvious. You have done well to think outside the best and come up with something that works for you but sincerely it cannot eradicate poverty.
