Eh. In these kinds of articles, the story is less “rich seize more wealth from others” than it is “assets already held by rich increase in ‘value’”. Almost everything in this article is “stock price go up” and, therefore, the somewhat imaginary “wealth” number of anyone holding that stock goes up. Basically, the headline could be “changes in stock price make the notional wealth of billionaires fluctuate”. Sort of a non-story to me, because everyone listed in this article could have done absolutely nothing all year, and these numbers would have changed regardless. More interesting (if only slightly) would be an article about changes to their actual assets (i.e. did they increase or decrease shares in their company, etc.). I don’t really get the “let’s keep score” for billionaires thing the media does in any case, but this article is on the more useless end of that useless pursuit.
