This makes a lot more sense when you consider that the vast, vast majority of accumulated wealth over the last 100 years is corporate wealth.
To depoliticize ... I would interpret this statistic as an indication of the correlation between wealth and corporate stock ownership, which is almost tautological. If you own or help run a public company you are probably very rich.
And even in the hypothetical case where more of the "90%" are benefiting from stock ownership than ever, this statistic will always simply highlight the reality that running or owning a business makes you money.
