One of the main reason is probably due to cultural differences – that's why people have diffrent relationship patterns and expectations. I come from a more collective culture in which people think about others, people can rely on each other, are honest with each other, authentic and relationships are deeper and only then can it be called friendship. Someone here says that he has a friend, and the only thing he has in common with him is that they will go out for a beer from time to time to have small talk.
Good luck in finding true friends.
