OK, now I'm questioning the whole thing... it also claims 17% of Boomers reliant on their parents. So, we have some substantial number of 62-80 years olds relying on their 90-100 year old parents? Seems unlikely.
It's plausible if it's an inheritable nest egg amount. Though I agree, seems unlikely.
Are they counting free housing as 'financial support'? A number of states have perverse incentives to delay the legal transfer of a home as long as possible, like with CA's Prop 13.
Wait until you see the homeownership statistics, or the average age of homebuyers.
Maybe you're not familiar with the entire economy? There are a lot of households that depend on retirement checks of the oldest members and households that don't have traditional work but may have family homes, businesses and farms still in the name of the oldest relatives. Different groups would have different results as far as whether they will inherit independence or become destitute if parents die.
