The real face of this society

I just feel so depressed. I had to go outside today to buy some garments for my siblings, I usually wear trousers and t-shirt at home so I quickly rushed and wore a dress shirt and unpressed jeans pant. We went to two different shops and everyone was staring at my pants, I felt a little uncomfortable but embraced my appearance at last. Then we went to the other shop and bought some uniform, I saw people around and got depressed somehow, I wasn't able to stand there, I wasn't feeling comfortable with their dressing and talks, it felt like they don't care about anything except themselves. Then we moved out, covered some distance, my brother parked his car outside a junk-food shop, many beggars came and I started feeling uncomfortable again. Their condition just broke my heart, what will 10rs or 100rs do for them? Today they eat and tomorrow they may not. They have no place to live, no shelter at all, whole families are homeless, they have no proper clothes or anything. Who's responsible for all this? Who should be taking care of them? I usually don't eat when anyone wants to eat in public, I just don't feel comfortable while eating in front of some hungry stomachs, it was hard for me to face it. I can be in their condition one day and I know that nobody will care. Tauba Astagfar-Astagfirullah. I pray for them. But their condition will always make me sad, they are the reason why I can't enjoy life, especially publicly. They're the reason why I don't waste food or money. I didn't own the car, it was my brother's, I didn't even pay for the snacks. But if I would be my brother then I'd not eat. We waste money and food, but we can't give more than 10rs to them! How inhumane we are. I don't earn, I am still a student, still I try to do charity as possible, still I cry for them. But when someone comes and begs, I don’t find the courage to give them anything, it's like I'm too broken to even say a word. I know Allah is the Razaak, He is the one who gives everyone food and money, but still I feel inside that it's my duty to feed and help them, which I'm unable to do, hence I feel empty and sad.
