All this "nasser has to have at least $2M to have the lifestyle he has" is just another glorified theory, and that's all. Let's come up with another theory with some numbers..
Nasser's first decent placing in a decent size pro bodybuilding contest was NOC 1994 where he placed second. The prize money there is still chicken shit. You get serious money only by placing TOP3 in at the Arnold or Olympia. Otherwise, the money you spend preparing for the contest will be equal, if not more than the prize money and you actually lose money.
Nasser's decent placings ended after 2000, so prize money from contest was a significant source of income only between 1994 and 2000. He himself complains all the time how he was unable to get a sponsor and how Weider finally signed him. Weider is not known to be the most generous sponsor, so let's be generous and assume he got paid $100k / year. I'm not sure how long the contract lasted, so let's just say he earned $600k in total with his Weider contract. And let's say, on average he earned $100k / year from contest prize monies between 1994 and 2000. That brings the total to $1.2 million. DVD sales, guest posings and such probably add few hundred grand to the figure. So, perhaps he earned $1.5 million when his career went well during those years. Take out taxes.. he's down to $1M. Bodybuilding lifestyle is expensive so during those years, his monthly expenses with living, car, food, drugs etc. must be at least 8k / month, so around $100k / year. That's $1M minus $600,000. He's down to $400,000. In his divorce, he loses half of that. The remaining $200,000 he uses to put a downpayment on his current house. Now he supports paying the mortgage by selling DVDs and worn clothes. Easy to earn couple of grand per month by overcharging schmoes. Car's a piece of shit, but it's ok because it's paid for and creates no monthly expenses.
The estimate above is of course pure speculation, and mainly to demonstrate that requiring $2M to have nasser's "lifestyle" is utter bullshit. You can do the same with $200k easy. There's no one single piece of "evidence" that nasser is a millionaire, but if he is, good for him. The numbers and his recent actions simply do not support that theory.
