Got $2,200?

This is an old article, but I just read it. Thought it was pretty interesting, to say the least.
Got $2,200? In this world, you're rich

• The research indicates that assets of just $2,200 per adult place a household in the top half of the world's wealthiest. To be among the richest 10% of adults in the world, just $61,000 in assets is needed. If you have more than $500,000, you're part of the richest 1%, the United Nations study says. Indeed, 37 million people now belong in that category.
• Half the world, nearly 3 billion people, live on less than $2 a day.
• The three richest people in the world –- Microsoft Chairman Bill Gates, investor Warren Buffett and Mexican telecom mogul Carlos Slim Helú -- have more money than the poorest 48 nations combined.
• The average wealth in the United States is $144,000 per person. In Japan, it's $181,000. Overall, wealth is mostly concentrated in North America, Europe and high-income Asia-Pacific countries. People in these countries collectively hold almost 90% of total world wealth.
• So be grateful for where you live in the world; it directly correlates to how much you have.
