Just a thought experiment. Imagine a person who always tells truth and only truth. They never lie, they never sugarcoat anything, never try to hide inconvenient facts of their biography from others. Whenever you ask them about anything (except for private stuff compromising their well-being, such as bank account data), they always give you a perfectly honest answer. They are not necessarily a jerk, but they will always tell you how they feel about you, even if it means telling you that they hate you utterly. Or, if they really like you, they will tell it right away, without any hesitation or anxiety.
Do you think such a person can be well off in the modern society?
