Really depends on where you are. These people won't get as far in stable communities where people know and talk to each other. If you are doing these things habitually as a way to get ahead, eventually everyone will figure out what is going on and will, at the very least, exclude you from the group.
This pattern is the case with most people who are especially dickish or unpleasant in one way or another. Sure, a very small number of them gain power and influence in the world at large. But most of them live shitty lives. They have few friends, and the friends they do have are shitty like them. They have no money, because they have trouble getting and keeping jobs - even low paying ones. When they manage to find romantic partners, the relationships tend to be tumultuous, since the only people they can attract are just as shitty as they are.
