Eh, dunno about denmark, but Norwegian books are like 3x the price of the same book in German. That's mostly because it's a small market that still needs translation, though. Doubt fiddling with the VAT will make much difference.

Joe Abercrombie comes to mind, bri'ish author, writes grimdark fantasy featuring amusingly dark and broken characters.

Sir Terry Pratchett, the man so funny and insightful, he waa knighted.

Jo Nesbø, if you're into crime/police novels.

Oh so many!

What are you into? Which country (I am personally partial to Russia, France, Italy)? Translated into English? Classics or recent?

For a nice laugh read Blindboy Boatclubs books, my partner banned the most recent one from the bedroom because I was waking her with my prolonged laughs

The Kalevala is great.

From the top of my head

The idiots should make more people read rather than just the wealthy elite. Problem is that if it indeed is so, most people won't complain sadly.

studies had shown that books were “primarily purchased by wealthier segments of the population”

This is basically universally true, the better educated read way more books on average.
The best way to give people with little money better access to books is free libraries of good standard.
If you are poor it doesn't matter much that the price drops from 10 Euro to 8 Euro. ( at 25% VAT. )

The price of books in Denmark is generally not a problem at all, only for the poorest it may be, for them better libraries is better.
Such a decrease in VAT will by far benefit the better off more.

What we need is to remove VAT on basic and healthy foods. We still have 25% VAT on all food. And vegetables are pretty expensive here in Denmark, AFAIK we are the most expensive country to buy food in EU.

I'm OK with removing VAT on books, but not before basic foods!

they never read about the chicken and egg situation

Well. Problem with small nations with a distinct language (I am Norwegian, and written Norwegian and Danish is basically dialects of the same language. Personally I hate reading danish and enjoy swedish. Think I am a massive outlier) is that you never get any volume. In all the Scandinavian countries large part of the population is pretty much fluent in English (guess the reading population skew even higher) so you have the added competition of English language books as well.
