Just so we're clear, you've read half of a book I hate - which is a memoir - and none of a book I love - which is a sociological analysis - and have determined that the book that I love is bullshit because you can't use it to create models?
Is that what you're saying? Because this statement is batshit fucking insane:
A Hillbilly Elegy is nothing but data about poor whites, a group that is largely misunderstood and oversimplified by our society, and as such I feel that it is hugely important to the communication of their condition.
There are two characters in Hillbilly Elegy and their only living relative dismisses the author's recollections of both of them as fiction.
