Retire on my own private island. Settle any old scores via Chimera.

Is there more or less total wealth in Shadowrun than today?
Again, define wealth. Purely materially, there might be more, but then again, with so much recyceling going on, notmuch at best. However, since there was VITAS, and many, many people died, and all kinds of wars and destruction, I'm half inclined to say 'less', if intellectual wealth and wealth in workforce counts.
QUOTE
Who has the wealth in Shadowrun?
It's concentrated at the top, but less in the hands of certain people, more in the hands of legal entities like megacorps that, usually, are public or shared private property. The social divide is much sharper than in today's West, more like in today's Brazil or South Africa. Not to say there are no oligarchs and other super-rich tychoon style people around, but it's not like there's more of them than today. I'd expect there to be less.
QUOTE
What do they spend their wealth on?
Megacorp things, mostly.
As for individuals ... depends on the individual. Dragons, spirits, sasquatches? Lots of things. Lots of weird things. Humans (thinking of Roxborough and Spinrad, this term is used rather loosely), however ... all of the points mentioned, to some degree.
