I think though allot of people need to learn what they can truly do with the money available to them though. Now your friend for example on $65k with a $200k mortgage.
Tax = around $14k Loan payment = approx $22k (@10% interest rate over 30 years)
Therefore leaves $29k to live off. Now to me unless he has lots of other debts this is more than enough for a family to live off of without having the wife go out to work.
