Wealth is a state of mind not a dollar amount. Adequate money to fund overhead and needs plus most wants. How much that requires depends on where you live, how important your wants are to you, and how expensive it is to fulfill them.
There are some for whom no bank account could be large enough to make them feel secure, never mind wealthy. Others live happily on barely more than the amount it takes to cover humble overheads. To me, the latter group are the wealthier because they don't let money run them.
