Proverty in indo

While every daily needs is increasing now.
especially recently from the Fried oil.. for cooking dunno what you call in english,
touching around 15.000 per kg.
i've heard a dramatic news. that cause it is so unaffordable , there are some poor people who cook with sand. . .
sounds awkward right?
but yes it's true . . .
when it's shown on tv, it can fried but not crispy result.
so what's next?

in indonesia, when it's poor it's very poor, but when the rich is extremely rich.
so there's no balance , i think the national developments should touch to this dilemma
