hey if you're disciplined, you may be alright. But history has shown that people in general will slip up. And they will eventually pay more than necessary to someone else.
Do you honestly think having cash on hand has more risk than taking on debt and leveraging it to future earnings? Sure there's wealthy people out there who've used debt to become wealthy. There's always a few. Look at the stats though. The vast majority of millionaires, the super wealthy, the ones who've worked for it, are not taking on debt. It's simple, debt means you're making someone else richer. Debt has more risk than just buying outright and owning. And if you've worked for your money, you're not just gonna give it up to someone else.
Most people have less than 1000 in the bank. It's proving my point. It's why there's a problem in the US. If you have less than 1000 in the bank, YOU SHOULD NOT BE BUYING A CAR. You should be saving, working, saving, working, rinse and repeat. You say buying a 500 car has more risk than having a car note. Again, YOU SHOULD NOT BE BUYING A CAR TO BEGIN WITH.
The whole car business you speak of, it's to make money. It's to get you to sign that line, THEY WANT TO MAKE MONEY OFF YOU. Whether it's interest rates, tax/title, registration, gap, extended warranty, etc. YOU ARE MAKING THEM RICHER.
Debt is like smoking. There's some people who smoke repeatedly, taking chances, who live to 100 and never get lung cancer. Then there's the majority who lose their teeth, get cancer, and die a painful death. The vast majority of experts in the field suggest avoiding smoking because it's hazardous to your health. How about being the person who avoids smoking and avoids risking to see where you end up? Just like taking on debt repeatedly.
