For some things sure. You need to have shelter for instance so it makes sense for that. You need to get to work and other places so a car makes sense so long as it isn't more car than you can afford (although I am going to pay cash for my next truck). You may need open heart surgery, the kid might need braces or the AC unit on the house might go out. Things like that are necessary and a lot of people don't have that kind of money on hand so going into debt for them might make sense so long as it is re-paid responsibly.

For an RC airplane? No way. Same goes for any other "toys" that are luxuries, not necessities.

Excessive debt will haunt you and make you its slave. If it is avoided life is much easier and you actually end up with more money and more stuff. It's funny how it works.

Think of credit and debt as a "product" because that's what it is. Banks and credit card companies are trying to sell it to you because they make money off of it. They are very good at selling it too making you think it is cool or even necessary. Would someone say that you couldn't live without any other product? Would my world crumble if I didn't buy Cheez-its? Of course not. Same goes for credit cards.

As for our governments operating on debt and deficits, that is a huge issue. It is why my wife took a 15% pay cut, CA parks are closing, convicts are being turned loose, police officers are being laid off, etc. When they are spending your money they really get out of control.

One of the best quotes I ever heard was something like "maturity and responsibility is the willingness and ability to avoid pleasure until you can actually afford it". Something like that anyhow. I probably got it wrong.
