How Much is the World Worth

Question

Seriously -- I mean if you just decided on a certain day and time -- like 10:00 a.m. on Dec. 31, 2008 --and wanted to know how much money the world was worth, at that moment, how would you do it? Is there any way you could estimate, down to the last trillion dollars, how much everyone and everything is worth -- add up all the debts and assets of every individual, government, and company in the world, at a given moment?

Answer 1

Net value.. next to impossible.

Value of lives.. impossible.

Answer 2

It would be nothing. Think about it - nothing has a set value, it goes by negotiation, supply/demand, purchasing power (physical ability, not monetary). Someone's debts are another's assets, and vice versa. Valuations are based on these factors, so there is no true value of the world.  

Answer 3

its like priceless...
