I get what you’re saying. There are ways to think that can help people feel happier or better on a personal, individual level. Thats more or less what some forms of therapy can do for people, and its a very good thing, again on an individual level.
But the context in that piece, and where i would put the emphasis, is that its an example of capitalist alienation and atomization. There’s no individual answer to that. It’s something that is pushed onto all of us through our relationship to capital, and to truely end that malaise, we need to work toward ending capitalism itself.
