This is pretty disingenuous and I'll explain why. The next 1% after the top 1% owns a pretty sizable chunk too. And the next 1% after that a large chunk, and so on.
The top 10% has 75% of U.S. wealth, the top 20% has 87% of U.S. wealth. So carrying on about the 99% as if wealth is distributed in anyway evenly within that group is more than a bit silly. Especially when you look at the bottom 50% having a pittance, somewhere between 1-2% of U.S. wealth.
The next natural group after discussing the 1%'s wealth, isn't the other 99% just because 100-1=99...
So really your argument falls apart for me because most of the 99%, the bottom 70%, end up owning just about 1% of the world's wealth. And that's a fairly small slice of pie to be split between 227 million people. And before you show me the math that it's actually quite a bit per person. Don't forget that in reality the bottom 60% only has almost as much wealth as the whole next 10% and that most of the population isn't seeing the wealth you're describing.
