Somehow, I think you missed that I pay my credit-cards down to 0 several times a month and have paid only membership fees ($39) and yet gotten several hundred $$ cash-back.
How do you support your above statement?
Yes, I did buy a new car, I don't think there is anything wrong with that, though. I'm not Amish (not that there is anything wrong with being Amish).
No, I didn't miss anything. To get cash-back necessitates your spending money in the first place. At 2% cash back, which is pretty rare for credit cards these days, it takes a lot of spending to accumulate several hundred dollars in cash back.
And I support my above statement with this whole damned thread. If I went point by point and wrote a dissertation, then it wouldn't be a summary
Essentially this thread boils down to the male version of the cliche oxymoron "Honey, I saved so much money shopping today."
