Retirement accounts are largely a benefit enjoyed by those well-enough off to have them [1], as well as owning a home. So while yes, these indicators have increased, it only speaks to how the bulk of wealth created since 2008 has gone to mostly well-off individuals. And while yes, wealth is overall heavily weighted to older generations, it does not change the fact that the only people who are rich are the rich, regardless of age. While most wealthy people are boomers, most boomers are not wealthy. If you look at economic insecurity (200% FPL), the elderly in America are over-represented, with a rate of about 33% compared to ~27% overall[2].
