I think my problem with Jack Monroe is that she puts herself front and centre of anything she's supposed to be highlighting, food poverty, fuel poverty and budget cooking. Everything has to revolve around her and how hard done by she is.
From what I gather she comes from a good family background, very well placed to embrace her in extended family after she gave up her lucrative job, but she chose not to tell them and then adopted the poverty persona that became her usp. Inevitably this, and all the inconsistencies in her stories, often trip her up.
I don't believe for one moment that she's wealthy, but the main point is that she's not as wealthy as she wants to be or thinks she should be, especially given the lifestyle she became used to with two of her previous fiancees and her latest partner.
I'm not aware of anyone charging for recipes posted on websites, but usually cooks or chefs like Nigella, Jamie Oliver et al, write books, sell loads, get tv series off the back of them, or vice versa and pick up brand partnerships and their own ranges of popular goods or food. They engage professionally via social media accounts and their websites for free and the whole thing keeps going around and around. By contrast Jack is unprofessional, her recipes often seem not to work, tv appearances are ill prepared and chaotic and so everything becomes very hard work and doesn't sustain the brand as well as it could.
It seems like she is being called upon as a poorly or non paid 'talking head' so she feels that she's famous and her value is far more than it really is, so she's constantly aggrieved.
