I'd be happy to school you.  There are wealthy people with low incomes.  Especially retired ones.  Take a retired executive with a $15M nest egg, lives modestly, and has an income of $40K.  Now take a younger lawyer with a $300K income, $200K in student loans, a million dollar mortgage, and a high-spending lifestyle.  Who is the wealthy one?  It's not what you make.  It's what you keep.
Glad to help!
