Answer:
Indeed I think our society is selfish with poor morals because people don't even care about others feelings. For example, there is a girl that win 2,000,000$ with help of her sister, but guess what this girl doesn't give credit to he sister and instead she said that she knew everything and she did everything all by herself. Another example can be: you are at the mall and you find 100$ in the floor, then you see that there is a person that is looking for that money, and instead of giving that money to the person you pick it up and go away. This is a pretty good example of being selfish and immoral. Instead of staying with that money you needed to give it to that person, I mean you didn't know if that money was the only thing that person had.
