That’s completely on the publisher. And they do it because, sadly, they get away with it thanks to mindless customers.

Nobody ever hesitates to pay such money for a game, so why would the publisher even try to lower the price? If they’re selling well at 80€, why lower it to 50€?

For me to pay more than 30€ for a videogame, it really has to be THE game. And it rarely is. Most of the time, I can wait a few months and get it at a honest price. Heck, even paying 30€ for a game it’s already something that I reaaaaaaaaaaaaaaaally consider carefully. Past the 20€ it has to be a great game for me to pay for it.
