I honestly don't think it matters. As much as I don't like my stepfather, he and my mom have been together since 1992 and my mom is the most voracious reader I have ever known. Hell, she reads more than me. I have never known my stepfather to read even a newspaper.
My mother once told me that in marriages, husbands and wives can complement each other by having what the other doesn't have. It could be that DB's intellectual nature inspires Brie to be more thoughtful and see the world in a way that she otherwise couldn't with someone else, whereas DB finds Brie's more woman of the earth character complementary to his, in that she may still work in an urban, capitalist environment, but still have her feet planted firmly on the ground, which is something he might not have been able to find in a city girl.
Now, as much as I adore the content of the videos that Brie and her husband make, I do have to wonder if they could be a little more discrete sometimes. Brie tends to be outspoken about spending habits and her choice of purchases and some hints of inadequacy are dropped from time to time.
I personally have nothing against her, no matter what she does or doesn't do. I would never use what I've heard her say as ammo against anyone, but I don't speak for everyone. Less sensitive or understanding people might decide to use this revelation against her, so without meaning to, she offered bullets to be fired at her. I'd be careful about what I choose to say on a public viewing channel because you never know who's listening. I never look down on anyone for what they do or say, and if they make mistakes, I know someone will help them learn to do better next time.
PS: I deleted some of the information in this reply because I divulged facts about Brie that offered the unsavory type information that could be used to belittle her without being aware of it. I only hope that what I posted about one of her segments hasn't been read by the hostile type. I quickly realised what might happened and edited out the disclosure.
