Does big money diminish a fighter's "hunger" or is it a "greed" thing?

I read this on Fightnews.com...... Former IBF super middleweight Jeff Lacy has revealed that he's retiring from boxing because he is insulted by a $550,000 offer to fight Jermain Taylor. "What do I look like fighting a fight of that caliber for $550,000 when I have more to risk than anything?" Lacy commented to the Tampa Tribune. "I feel like Taylor needs me more than I need him and what do I look like fighting that fight for $550,000 and risking my life in there like I did Wednesday night because the referee is not on top of this guy hitting me in the back of the head?" 1. $550,000 is a LOT of money. 2. $550,000 was the STARTING point of the "offer". It was negotiable. 3. Had Jeff Lacy taken this fight and beat Taylor, he would have been in a good position for a mega-buck fight next. I can't help but think that once these guys taste big money, they tend to forget where they came from. Most of us guys here on BoxingScene Forums would do almost ANYTHING for $550,000. But it seems like once somebody gets to the big time, has a huge payday or two, they start getting unrealistically greedy. Something else....two fighters that are universally respected are Tyson & Holyfield. Each has made close to $100 MILLION in their career and now, one (Tyson) filed bankruptcy and the other (Holyfield) has major money woes. Where exactly does $100 million dollars go??? Most of us will never see 1 million $ in our whole life combined. That's the same as saying that for every $ we ever made, those guys made $100.00 or more! And now THEY'RE almost broke. I don't understand that, try as I may. Boxing used to be free on TV. The 1980's peaked with great fights on all three networks (NBC, ABC, CBS). Soon as we fans started paying $19.95 for a pay-per-view, then boxing went off the major networks. Now, if you don't have HBO or SHOWTIME, we have to fork out $49.95 to watch a good fight on PPV. At what price does it end???
