Can we stop this small-talk culture in the USA?

One of the things I don't like in the USA is the small talk culture. It's just fake and a waste of time! I don't want to waste my time talking to someone if we're not going to be friends afterward. It's just a fake conversation and a waste of time. Some people try to believe that it's kind of friendly, but it's really fake. I don't want to be rude when I refuse to speak to someone, but people should also stop jumping to other people, talking to them, asking personal questions without even knowing them, and then just walking away! Like really? What a waste of time and fake conversation!
