Quick search;
Per pensiondaily(dot)com, 16.8% of the nation is retired. This doesn’t account for the % who have financially prepared for retirement, so let’s cut that % down 1/2.. roughly 8%

Add the 111 million in this article and we’re at 139 million

If you add all the categories this number will still be huge, but it will be about half of what the article says.
