You're right that people struggle with how much £1 Bn is.
Think about it as time. £1 gets you 1 second back in time.
1 million seconds is about 11 days. So for £1 m you could go back to a week last Friday.
1 billion seconds is 37 YEARS
So £1 bn takes you back all the way to 1988.
The richest man on the Uk, has £18 bn to his name in seconds that's 666 years.
His fortune takes him back to the Middle Ages. 1359
Musk? He's 'worth' 14,687 years. So his money converted to seconds would take him back to the ice age.
I think that's why people think addressing the increase in number and wealth of billionaires is the same as going after people who want to do well for their families.
But it really isn't. £1bn is a different league.
