Here's data straight from AMA's IRS 990's (public documents). This is in constant year (inflation adjusted) 2013 dollars. If anyone is interested in the raw data, I've got AMA's IRS 990's going back to support all the calculations / graph presented herein.

What's clear is that except for the years where AMA EC has increased dues prices, the EC has been unable to reverse constant declining membership revenue. And yet, while they knew the membership revenue was decreasing, the EC was voting to spend substantial sums of money at "Taj Muncie." It would also seem to indicate a failure of their organizational strategy, no matter how much lipstick they try and put on this pig.
