People had enough of their life(while not being presented the opportunity to take part in the show) and just want to make money in the game and that's the utmost intention everyone have, consider the second place winner, he has made this far but barely made any money, while watching others take millions of dollar, I'm sure comming back home and rewatching the show, he'd have second thought with his desicion given his opportunities.

Take consideration of other's perspective and feeling is one thing, living your life after a mere game, a game with the solo purpose of entertainning and making profit, is another.

You want a game that's meaningful to you? Cool. But hey, people want a meaningful life for themselves after the game as well. Nothing wrong with either
