Why is Gen 3 night vision still so expensive?

Now that digital infrared cameras can be found for under $100, and decent thermal cameras are under $1000, I thought I'd check on Gen 3+ image intensifier optics. They're still over $3000/tube! Why hasn't the price for intensifiers changed in the last 15 years?
