Think about it like this.
You take out a loan, now you owe someone X amount of dollars and you have a limited amount of time to pay it back. They officially have power over you (financial). Now say you gotta pay $250/month for a loan. Think about where else that $250 could go if you were not in debt. Also, you have to pay interest. I don't know about you, but I don't like paying more money than what I'm supposed to at all. Quick example, if you took out a $5000 loan, would you rather pay back $5000 or say... $6213 (random number but hopefully you get the concept)? Banks are a business at the end of the day, and if you miss a payment, then you're going to be in some serious trouble. They'll take away whatever you got the loan for, you're credit score is going down the drain, and in some cases, it could lead to a lawsuit (like when people buy cars that have been repo'd). I say the best thing for all of us to do is to stay out of debt. I think about how much money I could have had if I never would have gotten into debt, and now I'm changing that for my life and will use that to build myself up in life, especially now that I'm in college. So to answer your question, yes all debt is bad. The only person that really even half-way benefit from debt is the lender, and I say half-way because they loaned their money and we do have some people out there who try to be low-down. So try to avoid debt at all cost.
