While there is a correlation of net worth and age, there is no age band [0] where the median net worth is even 2/3 of the 75th percentile population net worth. [1]

Age is not a major explanatory factor in wealth inequality. (The fact that the mean income in the 35-44 age range is much greater than the median income at the 65-74 age range, that has the highest median of any age range, also underlines this.)
