Sorry, Jack. What you’re describing is largely cultural, not “human nature”. The issue is far more complex than what you present. Empathy is both innate and taught. Society can encourage and discourage it. Perfect example of this complexity in the US is the meanness of spirit toward homeless people and the opposite generosity to disaster victims.
Plus the ego-centric view you describe here is also very Ameri-centric, and represents an extreme position on the spectrum of ego development. Many other societies have a far more community- and collective-based sense of self, and hugely different personal interaction styles.
As to the value of therapy, as a former therapist myself, I can tell you that the reality is also far more complex. Whether therapy is valuable or not depends on the quality of the therapist’s training (many psychological schools have inbuilt biases), plus the therapist’s own awareness of their personal issues. Some are sadly clueless. There are many studies that show that therapy has essentially no effect on recovery time from trauma.
Hence the wise advice to shop around, ask probing questions, and choose your therapist wisely…
