How much is a billion

How much is a billion dollars? How can you visualize an amount of money so high? Here is one way to think about it: The median household income in the US is around $50,000, meaning half of American households - everyone in the house combined -- make less and half make more. If you make $50,000 a year, and don’t spend a single penny of it, it will take you 20,000 years to save a billion dollars.

In the US 400 people have as much wealth as half of the population.

The top 1% also own 50.9% of all stocks, bonds, and mutual fund assets.
