…Ms. Petersen has, it seems, constructed an entire worldview around being irritated by small errands … Her diagnosis may be overbroad and unconvincing, but Can’t Even can serve as a guide to a class of American adults who are replacing life’s mediating institutions with careerism and political activism, to no great result … Ms. Petersen is a shrewd observer of other trends as well … Less credible is Ms. Petersen’s story about the economy … Ms. Petersen’s claim that millennials are worse off than past generations is also complicated by today’s wildly higher consumption levels, which makes comparisons difficult … Part of the author’s goal is to push back on stereotypes about millennials, but Can’t Even often confirms them … offers no policy solutions to the millennial life of overwork and overstimulation … Blaming, as this book does, capitalism, Donald J. Trump, management consultants, patriarchy, Instagram—all of that, and nearly everything else, is easier than facing up to the significance of one’s own choices..
