That's not a common definition of poor. This is one that would be more in line with typical use:
> Lacking sufficient money to live at a standard considered comfortable or normal in a society.
>Poor is where you must work to maintain your lifestyle.
Said no one ever. That's almost insulting to people who have actual financial problems.
Rich is where your money makes you enough money to a point where you need not work to maintain your lifestyle (but can choose to).
