While I certainly agree that one should always manage their finances to allow for retirement savings, I want to point this out;

"People who bought a first house in the 1980s or the early 90s had their hands full saving for retirement because of high interest rates. But whereas these buyers got to enjoy steadily falling rates in the ensuring years, today’s buyers will likely face rising costs over the decades it takes to pay off their mortgages."

So folks like me that bought in the 80's benefitted from falling rates, we did have to deal with initial mortgage rates in the double digits and falling rates of returns on our savings over the years. 

Conversely, folks buying now have low interest rates on their initial mortgages with rates that will likely rise over the years, their savings should also benefit from the same rising rates.  (should that occur)

Both generations had/have problems and benefits from their respective rate environments.
