There's a familiar critique of all things "self-help" that is no less accurate for being old: it treats structural problems as if they are personal ones, and in doing so, both makes us feel guilty and pushes us towards individual, rather than collective action.
But, though they reinforce my sense of isolation in the world, self-help books (and podcasts, etc.) do at least make me feel I have the power to improve my situation, whereas most books/podcasts/etc. I've encountered that take seriously the interlocking structures that oppress us are pretty disempowering, because they are enumerating all the interlocking structures that make it unlikely that I'm going to get healthier, happier, and more financially secure on my own.
Books (etc.) in this second category generally don't just leave you hanging in despair, they call for a collective response to interlocking systems of oppression. The problem is that (child of a neoliberal age that I am,) I don't, in my bones, believe in the potential of collective action to change our world. That's not to say I'm not trying to make it happen, but when I read a sentence like "this will only happen if we radically transform the world", I translate it as "this will never happen." This is why on a fundamental level I've never understood the people (often but not exclusively Marxists) who dismiss reformism and insist that nothing short of revolution will meaningfully improve our lives. I worry that that's the case, my belief that it isn't the case is grounded on my need to feel OK-ish in the world rather than a well-thought-out evidence-based argument, but I just don't know how I'd get out of bed in the morning if I believed that.
I've encountered a few books that offer "self help" within a context of our interconnected web of being. How to Do Nothing by Jenny Odell comes to mind, and I know these are others but I wrote the first version of this post in a notebook in 2023 so I'll need some time to recall other examples. If you read this and would like to add suggestions in the comments, that would be wonderful!
