Personally, while I don't think debt is evil exactly I think it is a major cause for problems our society faces. People are told the same thing you are saying, debt is ok if it's low interest and you can use it to afford nice things. That may be true, but it is also neglecting two important factors: risk and liquidity. The more debts you have, the more trouble you will be in if you ever lose your job. The more monthly payments you have, the less net income you make each month so you can't afford to do anything because all your money goes toward your payments. Then, you feel like you have to take out even more debt since you have so little coming in on a monthly basis you can't save up.
People get themselves into debt up to their eyeballs and they rationalize by saying it's 0% interest or it's low interest, or this is a good investment. Then, they feel much poorer than they really are because they can't afford anything beyond their monthly debt payments. It's the way society would have us believe we need to live, every message in every advertisement says to go ahead and take out loans. I'm not saying you personally do this, but there are millions of Americans who do and it's really sad to me. I don't think anyone should ever be told to take out debt without a very strong need. Debt should be a last resort during tough times or a calculated business move, not a way to afford consumer goods.
