Basically you take the average or median lifetime income of normal everyday workers (i.e. those who leave school around 18, go to trade school, and work until retirement), and then you compare that amount of money to the income or wealth of a rich person.
That way you can see that for example Jeff Bezos makes 1.43 million $ an hour - about as much as the average American makes across their entire life. A shocking disparity.
He made $1.43 million an hour from stock appreciation in a specific year. We didn't see similar headlines when he lost $20 billion+ from a stock slump; "Bezos Loses $2.3 million per hour! plans to commit suicide..."
You have a good point about wealth disparity, but thanks for spreading clickbait..
So even if he loses 20 billion a year, even if Elon Musk loses 40 billions of dollars in a short time, nothing changes for them. They still have tens of thousands of times more money than a normal human can make.
I suggest median expected lifetime earnings.
