I think the rich have more to fear for the future since losing the game could mean a drastic change in their lifestyle. Luckily for them, they are also better equipped for handling such situations. Many are financially literate from a young age and has probably worked in the family business and have a network from college and other social circles they've been in.
For us poorer folks, it's really just going day to day without much sudden change.
I'm sure the rich man has a greater fear about the future. The fear of losing what they have already achieved and the personal egocentry towards the high society are worse than the fear of not thriving financially during a lifetime for the average poor on his confort zone. The rich has too much to lose, so he will care much more about his finances, while the poor has nothing, so for him anything the future holds is acceptable. It's common to see people suiciding after going bankruptcy, while we rarely see people suiciding for being poor. There are exceptions in every cases, but basically these are the most common behaviors of riches and poors I observe.
Can't argue about the suicide but I think that was more because of the stigma in that social circle of getting bumped down several tiers. The poor might be ridiculed by those on top but not by their peers since they're all at the bottom anyway. For those on top though, some just can't get handle the humiliation.
