While price per piece may have remained relatively constant, Lego has been pushing out more and more expensive sets. I remember when the most expensive set was the 400 dollar death star, and that was the only 400 dollar set. Now, there are 26 sets that are 400 dollars or more, with 7 of those sets being 600 dollars or more, and the most expensive set being 850 dollars. All of this to target more adult fans of lego.

Note that the $400 death star (set 10188) was released in 2008, and $400 in 2008 dollars is worth $570 in 2023 dollars.
