Why are M.Arch fees so high compared to other graduate programs?

I am looking to pursue a Master of Architecture abroad.

I’ve noticed that M.Arch programs typically have very high credit requirements (usually 60 credits for 2-year programs, and even more for students without an architecture background).

On top of that, the average per-credit cost for architecture programs also seems much higher compared to other fields.

Why is this the case? Is it due to the resources required, the program structure, or something else?
