"In 2013 we estimate that 3.2 billion individuals – more than two thirds of adults in the world – have wealth below 10 000 dollars."[1] In total they also estimate that those 3.2 billion individuals have a combined wealth of 7.3 trillion dollars.
So, unless you're implying that everyone who has "a checking account" has more than 7.3 trillion dollars, sorry, it's just not the same.
I'm not denying that there is extreme inequality between poor in America and poor in Africa or India.
But let's not make false comparisons between having a banking account and being in the top 30 wealthiest individuals. Having a banking account is not the same as having 7 trillion dollars in wealth.
