Personally, my highest was about 325-330K for a year. Fortunately, that's started to be curbed back a bit. And, yes, I am a consultant who is now in a position to start farming stuff out to junior partners and able to focus a bit more on administrative issues.

I can't imagine doing 800K/year. After doing 300K+ for several years in a row, I didn't want to see the inside of another plane and if travelling didn't ultimately have an impact on my wallet, I probably would have stopped getting on those planes.
