What should we spend our money on?

I was watching the youtube video "World on fire" exspecting something about something were doing wrong. But it was about what we use our money for and what that money could be worth in other places around the world also what we take for granted. We could pay one editor or we could put onehundered kids in school in Tanzania for a year for the cost of $2,500. Which would you rather pay for? Another part of this youtube video was about a woman who works two jobs sixteen hours a day seven days a week. One of her jobs is sealing oranges she sells each orange for two cents she normally sells fifty oranges a night on an avarage so she would make one dollar a night. She make aroound twohundered dollars a year just so she can send her kid to school. That makes me feel so greedy because compared to her life my life would be a dream to her even better that a dream. I also never realized how lucky I am to go to school every day. After watching this video made me rethink on what I should spend my money on.
