While it is certainly true on some level, I think Carnegie chose not to use "manipulate" for a reason: It's not so much about getting them to do what you want, but to see the issue from all sides and choose a path that is beneficial to you both. He also repeatedly stresses honesty ("honest appreciation"). So even if there is some amount of manipulation, it's still mainly about seeing everybody as a person and working together.

Here's a chart I found useful for translating the precepts of the book into a more actionable form: https://labs.thesocietea.org/carnegie-chart/

The book the 48 laws of power is about manipulation which I don't like. I consider Carnegie's book, The 7 habits of highly effective people excellent books to learn how to help other people through win-win situations.
