Whoa. That whole (no pun intended) underground is too much drama. Then again, bodybuilding is dramatic. Drama.
There is more happening in the “underground” than above ground. Think about: bodybuilders are on stage or being photographed for magazines, etc. for a few minutes at a time. What do you think they are doing with the rest of their time? How are they making their money? Travel, food, supplements (legal and otherwise), etc. cost money! Throw kids or child support payments into the mix and even someone with a legitimate job and a salary is just barely making it.
Where I live, a single person with no children needs about $100k to live a reasonably comfortable life. I know there are less expensive cities all over the country, but seriously, do you really think anyone can make a living as a bouncer? And how many bouncer jobs are out there anyway? Most bodybuilders are not college educated and do not have what many of us would consider a good job. Remember this guy who was living with his brother and working part time in a rec. center?
http://www.getbig.com/boards/index.php?topic=281208.0Look at public venues like musclegallery.com, rentboy.com, or Jimmy Z’s muscle-jam and remember for every one you see there are dozens you are not seeing--and not every venue is public. Hell, even Nasser was selling his used articles of clothing to schmoes and he was pretty high on the totem pole as far as pro bodybuilding goes. Nasser, Titus, BSA... I'm not saying everyone is a male whore, but for better or worse, many thing$ happen behind closed doors.
