Does it sound natural?

My grandfather always complains about how less friendship people are together today than previous. Based on many sayings like this, I believe that people's humanitarian feelings have decreased over time. Nowadays, people are less kind to each other than people did in previous. As a consequence, nowadays people are less willing to help needful people specially needful people they don't know. Here are some reasons for this that I'd like to share.
The first reason that I'd like to mention is that nowadays people trust each other less than previous. This is because people increasingly face with peoples who pretend they are need ful but actually they aren't. For example, I have frequently faced with people who claim that they lack their principal needs like clothes and food, but when I look closely, I realize that they are drug addicts and they wnat money for butying their drugs.
There are also some other examples of burglers who abuse people's humanitarian feelings. Although it is rare, but some burglers pretend that they badly lack their initial needs like food and clothes. But they are actually rich.
When people cannot don't trust each other, they prefer to give their helps to charities where they can trust more easily.
To summarize, I think nowadays people less tend to help people they don't know because the interpersonal trust has decreased. While this situation leads people to help needful people indirectly by giving their helps to charities, I think returning to the past tradition, rather, meeting and helping needful people directly more appropriately satisfies our humanitarian feelings.
