Debt free is great, but not the end-all-be-all.
You won't convince me that having some debt is bad and will be the ruin of me or anyone else who manages it wisely.
My wife and I have nearly polar opposite approaches to money, but we make it work. We each contribute equal amounts to out "joint" account and that goes to pay our mortgage, utilities, emergency fund and vacation fund. Jointly, the only debt we have is the home.
Beyond the home, my wife does not believe in and has zero debt. She buys what she wants and socks a bunch-o-cash away into investments and savings.
Besides the home, I have one debt which I recently took on to buy my new motorcycle. I bought it because I wanted it, because I can afford it and because I got an interest rate below 1% for the loan.
Beyond the home and bike, I have no debt. Truck is paid off, credit cards are paid in full each month, my personal emergency fund is set, I contribute the max allowed to my thrift savings plan, fully fund an IRA, have money going to an annuity and a long term savings account.
Sure, I could have waited on the bike until I socked away enough in another fund to pay cash for it. I could have taken money out of another account to pay for it, but when my interest rate on the loan is less than what I'm getting back on my money, I'd be losing.
Debt is not always bad.
