It's interesting your prospective and I think we can open a debate on it.theres many aspects to it, comparing numbers is just trying to keeping it up with the joneses.
For some its not having a boss, which makes them feel wealthy. Or being able to travel freely or sleep until late and work during the night.
a good starting point is being in the 1% or even 0.1% where you physically are to be less subjective and if you want to put it in that way (mainly used in the to-be-obsolete banking realm).
Each person has his own prospective, so the perception about this is different so anyone.
It's curios to know the definition of "wealth" from everybody.
