But make sure they know who has the money:

HELSINKI (Reuters) - Two percent of adults have more than half of the world’s wealth, including property and financial assets, according to a study by the U.N. development research institute published on Tuesday.

While global income is distributed unequally, the spread of wealth is even more skewed, the study by the World Institute for Development Economics Research of the U.N. University said.

“Wealth is heavily concentrated in North America, Europe and high income Asia-Pacific countries. People in these countries collectively hold almost 90 percent of total world wealth,” the survey showed.
