Read the Book. More or less it sais "How to be an effective psychopath".
Its easy not to complain when you are all set up. It is also easy to bash on others when you are all set up. It sais so in the book. If you follow what the book sais really you effectively become an empty shell of hypocrisy that treats others like tools.
If you say to people that you are treating them much like the books outlines they will crucify you. How does that make you feel about who you are and your purpose on this planet?
There will always be those who want to burn the village down. I am not one of them, never have been and never will be.
That does not change the fact about you being aware of a given situation. You can't just use and abuse people and respond with "Well, there is always to be suffering in the world".
Those kind of books are not very...enriching really. Literally every single dictator, every living, breathing asshole that has lived, used those techniques. If you are to be intellectually honest then you have to outline to the people you engage with the tactics of that book. That takes balls. Anything else is hypocrisy and your demise can come at any moment once people realize this.
When for example someone asks you, your opinion about something and you respond "These topics are polarizing so I am not engaging" you are actively admitting that you don't care about the people with whom you interact with, what they believe, what their views are, and rather use them in your marketing plot to make money out of them. You don't care for them as people to have "real interaction" bur rather you see them as specifics assets for a specific purpose.
You see, many people read these books and many people are always a step ahead from those who chose to use techniques from books that look like they have been written by an angry teenager.
The status quo is encouraged by those that already benefit from it. The village need not be burned down necessarily but ostracising those that question the town planning reduces dynamic and beneficial growth for all. Listening to criticism and swimming in the miseries of others are two very different things.
