??? If the $104k family spends $20k on a private school they still earn 3x as much as the $30k family.
This is so geographically dependent. The $104k family in my area can do a nice house in the neighborhood with the best public schools, an private for a kid or two also. They certainly can spend $10k on a college consultant if they want to.
The $30k family is not likely to have much extra at all, but around here even that family can probably swing YMCA or rec sports team fees. Not the house in the nice school area or the private school though, and definitely not the college consultant.
