Respectfully, I disagree with your statement. The most obvious example is home ownership or buying a car to commute to your first job.
Yes, it may mean paying interest on purchases (don’t forget interest-free deals you can take advantage of), but would you say to a new homeowner that buying a washer and dryer on credit is a bad purchase if it allows them to wash items at home rather that the time and expense of using laundromats? (Don’t forget gas and mileage costs.)
I happen to use a credit card for all purchases and pay off the balance each month. I have been getting 2% back into my children’s college fund and it resulted in over $10,000 in money the card company gave me for using their service.
Credit, if used wisely, is an incredibly powerful tool.
buying a washer and dryer on credit is a bad purchase
YES I Would, Buying ANYTHING on credit with the exception of your home is always a Bad Idea. Home Mortgage is the Only Debt I have ever had. And even then you should do everything possible to pay off that house as fast as possible. I payed off 1 in 8 years and the other in 1 year, paid cash for the other one. I was only able to do this by NOT GOING INTO DEBT and SAVING MY MONEY. But what the hell do I know, I have 3 paid for houses, 2 boats, 2 airplanes, 12 cars and trucks, 9 motorcycles and NO DEBT with a $150k Income. The world could collapse tomorrow and I DON’T CARE because I owe Nobody Anything.
