Overall, this is a great overview of personal finances and how to operate within the U.S. system of capitalism successfully. It's all the things you wished you had learned in high school and/or college.
My central critique is that the feminist angle felt overly simplistic. It felt geared towards middle-upper-class, cisgender and heterosexual women. Unfortunately, there is a certain amount of privilege you have to have to begin building wealth through investing (i.e. some savings and/or extra cash flow, work with benefits, etc.).
