If you always pay off your credit card in full on time, then it's effectively the same as a debit card that has fraud protection and cashback built into it.
There is a really simple way to avoid getting behind on your payments: don't buy things that you can't cover with the money in your checking account, and pay your bills on time. Heck, if you can't do this with a debit card, you'll get socked with overdraft fees that are on par with what the credit card would get you for.
The problem isn't the logisitics of paying the balance on time. The problem is how easy it is to get into a situation where you get (even slightly) behind the ball.
I don't want to argue with you about it here. This isn't the right place and maybe the debt trap is something you have to witness firsthand to appreciate. I would submit that if it were as easy as a checking autopay, then this wouldn't be happening: http://www.mybudget360.com/american-middle-class-debt-serfdo...
