Yes, the article conspicuously failed to "run" any "numbers" on this point (or on any point, for that matter). What are the risk profiles among different age groups? What kinds of distributions of risks are there? How did each group fare before and after the reform? What are the average expenses in different demographics and how do they compare to the premiums (in different demographic & income groups)? None of that is here, because this is not an analysis, but the "Forbes blog" formula: linkbait title, no followthrough. The article doesn't even mention the most obvious change, which is that the big policy change in Obamacare was removing preexisting conditions as a pricing differentiator. That has a fairly complicated set of results, some of which correlate with age, and some of which result in other kinds of pricing changes (such as a transfer from people who did not have major childhood diseases to those who did). How much? The article doesn't investigate, because it did not in fact "run the numbers".
