Just for some comparison, wireless Xbox 360 controllers sold in 2006 for US $50, PS3 controllers slightly more, and Wiimotes as low as US $40 (without nunchuck/motionplus).
PS4 controllers were $60, Xbox One controllers were slightly less, and Switch pro controllers were $50 (more comparable than comparing to Joycons).
Now Dualsense controllers for PS5 are $75, Xbox Series controllers are $65, and Switch 2 pro controllers are $90(!!).
US $1 in 2006 is the equivalent of $1.60 today when adjusted for inflation, so that $50 Xbox 360 controller at launch would come to $80 now. Not that those figures necessarily translate into buying power, but it does seem that (Nintendo aside), the price is keeping pace or just shy of inflation.
Nintendo's sharp jump from the cheapest to most expensive option is likely factoring in inflation with anticipated tariff adjustments during the console's launch...which they'll never walk back even with the scary numbers gone.
