> the first one being no one without their highschool diploma or G.E.D. (General Education Diploma) should read it.

Could you unpack this for me?

I suppose parent poster means that people who haven’t finished high school may take it too much at face value, and not take education seriously.

Correct. My concern is if young folks, such as when I was in middle or high school, read this they might become too underachieving.

Okay, the age at which somebody is exposed to certain media seems like a potentially valid concern. I thought you were making a statement about adults who hadn't obtained those credentials, which would be a whole other bag of worms; it's possible to attend college without a highschool diploma or equivalent, and it's also possible to achieve difficult things without either of those pieces of paper in hand.

On Amazon UK the book has three ratings, a four star, a three star and a one star. Which are labelled 28%, 45% and 27% respectively. Wtf?

Interesting and WTF for sure. Must have rubbed some people the wrong way...

Reading it can be frightening for overachievers and people whose world view and beliefs (the upper class who need servants) requires we have people working for them otherwise their materialist and GDP/economy driven world views might cease to exist...

It's more that the percentages, whilst adding up, don't match.

What if it's an easter egg / joke facilitated by Amazon employees... making their calculator [perhaps only for this book] perform incorrectly... hence underachieving?

Maybe it's an easter egg yolk.
