i doubt anyone here is saying to accumulate debt to reap the reward of cash back. you pay your balance every month and the cash back is a bonus. i guess it may seem insignificant to some, but i usually get about $1800 a year from my bank.
I wasn't really talking about going into debt to rack up points. With the financing thing I was talking about people using the "interest free financing" or "no payments for 90 days" type stuff. But charging everything also carries risk. Say you finance a shiny new Apple laptop and you charge everything on credit cards every month. Then you suddenly lose your job. The first month, you think "Just to be safe, I'll only pay the minimum payment on the card until I get back on my feet". A couple of months later, you are still unemployed and your savings are rapidly evaporating, so you put a few things on the card. Oh yeah, and you only have a couple of months let on that "12 months interest free financing" on that shiny Apple laptop. When you do finally get back on your feet, you are staring at a nice pile of debt. You didn't plan to do it, but life happened.
My point is this: taking on debt is taking on risk. I just prefer to eliminate risk when I can. I went through all that stuff, except I didn't pay the cards off every month. I had the typical attitude that if I could make the payments, I could afford it. Yeah, a lot of it was my own stupidity, but I just don't care to ever have that feeling again.
