When some of us individually have a greater net worth than groups of countries, yeah you'd think it wouldn't be too hard.

The entire wealth of the world is only about $46,000 per person (this includes things like the value of homes, personal assets like cars, etc.)

To be a little less tongue-in-cheek it seems to me that it is less a problem of scarcity and more a problem of distribution. Food, for example, is this way. Land, by and large, is also.

Can you give an example?

I am being purposefully hyperbolic in response to the parent's hyperbolic sarcasm, but for example Somalia, Burundi, and Madagascar together have an estimated GDP of about 40 billion dollars. Forbes billionaire list contains 19 people with a net worth north of $40 billion.

You realize that GDP is a flux right - it has units of $/year, while wealth has units of $? It's textbook economic illiteracy to compare wealth to GDP.
