Good Point - but double income is just part of it. The other parts are: - ZIRP and resulting housing price increases - overleverage on housing, driving up housing prices - mainstream acceptance of spending 50% of income on housing in many markets

But your point remains -- costs are out of line from our parents' generation. I cannot afford to buy my father's house even with 4x the salary he made. Salary-Housing multiples are insane and drives people to make poor work choices.
