Welcome to the third world

So I live in México and people usually come to my house to ask things, like clothes, food, etc. There's a poor neighborhood next to mine, so they come a lot. I was doing nothing using the computer, when someone knock on the door like 5 times. At first I thought... sigh 1 time would be fine... I opened the door to find 2 kids, they were like 8. The kid asked me if I had something, he said an apple, a banana, something? I broke my heart idk why if I had seen kids like this all my life, they always come. So I went to the kitchen took 2 oranges, 2 little boxes of cereal and 2 glasses of water. And gave them to them. Then I saw a woman and she asked me if I had clothes, and I told them the truth my mother hasn't take anything away. The kids were already walking away, when the boy turned back and said, thank you God bless you... I just said, God bless you too.

I don't know why, but when I closed the door I felt like crying. I see kids in the street asking for money almost everyday, people come to my house to ask for things and I've seen people looking in my garbage for things. I'm kind of used to see this. But I'm thinking since when it's normal to see starving people in streets, when there're so many rich people. Since when it's okay for a kid to work all day and walk to every house to ask for food, when they should be playing. It's not okay and I wish more people would see that. I wish people, powerful people would do something to help. It's not okay and it breaks my heart. :(
There're so many rich people here, the richest man in the world is Mexican, and there're so many people out there starving and homeless. I wish I could help but Id on't know how. :(
