26.9% of wealth distributed amongst 26.8% of households -- firm grip indeed.
The "news" is that Gen X is joining the other groups, pulling away from Millennials.
The numbers that we _should_ be looking at is not how much they have vs how many they are (ie the wealth per capita) but wealth per capita at different stages in their life vs same stages in other generation's lives. Compare how much wealth per capita boomers had in their mid twienties, mid thirdies, etc compared to younger generation. I feel those comparisons are much more fair and telling (and yes, AFAIK, there is a discrepancy that makes it seem unfair).
