I was working for Arthur Andersen and later KPMG in New York. The technology stack was varied (Vignette/TCL is one odd example) and largely irrelevant to my rate, as was my value as a programmer (I wasn't very good back then). $325 was one of my more sedate rates actually, they've billed me out as high as $400.

People tend to think the crazy numbers were a byproduct of the internet bubble but the biggest factor was due diligence: certain big clients had to choose a Big 5 firm for their projects based on requirements such as, minimum number of employees, minimum years in business, minimum assets, etc. The whole racket was absurd, if you ask me.
