The core of stoicism (stressed more by Epictetus, a former slave, than Marcus Aurelius) is that we should not focus or worry on things we can't control. We can't control other people, or societies, or the unforeseen tragic events we may experience, but we can control our own actions, our own thoughts, and the way we respond to them. We can't dictate our emotions, but we can handle how we express those emotions.
In many ways, it's similar to what you might learn going through therapy. But the mental health and difficulties that men face are somewhat overlooked by society and not taken as seriously as maybe they should be. In that environment, literally any strategies at all for dealing with stress and anxiety that are tailored towards men are going to be popular.
And for the capitalists upper class what it does is to validate the atroicities they commit: "the universe is an eternal good entity, everything happens for a reason. Sixty thousand children killed in Gaza? Its just the universe changing colors, changing quantity, some people turned from alive to unalive, but in the grand scheme of things it doesnt matter. You are just doing your role".
If you're upper crust and controlling everyone beneath you, I think it's still worthwhile to consider stoicism. Or is there some kind of divide - if one is poor you should enact one set of philosophies, if you're rich and powerful one should enact different philosophies?
Will that help your situation?

I usually give people John above. I tell them to ask God to speak to their hearts about the truth. Then, read it all the way through. Ask as you read: "Who is Jesus? What is our problem? How does He say we will be saved? How do we live?"
Considering the popularity of Ferriss, he is probably part of the reason. I suspect the type of people who read his books (eg the 4 hour work week) probably are into it too as it is a macho stance to take. Who the hell thinks it is good to sleep on a stone floor in order to toughen your mind so you don't get too attached to comforts? My philosophy is I'll deal with suffering when it comes, and not practice before then to get good at it.
It reminds me of an interview many years ago with Jim Rose, who put on a traveling sideshow circus. There were no tricks -- the performs just did strange, painful things for entertainment. One of his routines was his wife would throw darts, using Rose's back as the dartboard. The interviewer asked, "Do you practice this?" He replied something like, "Hell no! It hurts! I did it once to see if I could do it, but after that I only do it for the show, where I get paid!"
