So after taking in that heavy video, I pondered these questions:

 "If all the world's wealth was shared out equally, how much would each person have?"

 -The answer according to Mark P. via Yahoo is:

 "In US dollars, $65000000000000 (65 trillion) is roughly the amount of cash in the world. The latest estimates say there are 6,600,000,000 ( 6.6 billion) people in the world. $65000000000000 divided by 6,600,000,000 people would mean each person has a worryingly low $9848.48! I hope that helped answer your question :)"

 -The answer according to Carlton C. via Yahoo is:

 "...As such, it would be hard to answer this question. There are approximately 963(+ or - 10) Billionaires in the world. If them and all of our millionaires distributed their wealth evenly, we would all be right back to how it is now in a few years :-) Wealth is a mindset, not an amount of money... To your success!

 "How much would it cost to eradicate poverty and disease in the world?" 

-Nikki on Yahoo says:

 "$964,784,270,408.00 thats billions but who really knows..... Source(s): source:money solves all problems"

 There is no real 100% accurate answer but I think you get a rough idea. I chose not to follow a scientific source because even science has room for error and we are all equipped with common sense. For me 10,000 is not low. I have yet to see my own account with more than 100! Think about this....10,000 could buy a lot of things.

 "What could 10,000 dollars buy?"

 Here's some answers:

So what do you think?
I'm inclined to believe that, sans the politics and social structures, there would of course be personal motivations and we could be right back where we started. However, since we as people, have imagined quite a few things once thought impossible. I say why not entertain the idea of a huge change in quality of living for everyone?
When you have to face scarring visions of poverty daily, deep down inside, there has to be some reasonable solution. 
In this world of "failing" economies and greedy hands, we still remain. For how much longer, who is to know? We can do something, even if it seems little. 
I invite you to take these subjects into your  conscience and ponder your own solutions. If you take action, then we are all that much closer to a solution. If you do not, we remain headed toward a destination that maybe no one wants to see.
Peace and Respect and SUCCESS,
