rent<=1 week's wages
is gone forever. Most people I know anymore have rents that take >1/2 of thier pay (some >3/4). Many have real credit card problems - aquired when times were better (myself included).
Only multiple incomes in a single dwelling alleviate this; remember that budgeting without accumulating signifigant savings insures the eventual slide downhill into poverty. Emergencies happen - and expenses cannot always be recouped via insurance or legal recourse.
