You disagree so the logic is flawed. Excellent.
My news is all red regardless what I do, but it makes no sense to pay rivals. This is the same reason I have always banked. There is no good reason to pay rivals to attack me, just like there's no good reason to pay rivals to rob buildings I don't or can't collect regularly.
I earn a lot of cash with the buildings I can and do collect regularly, so I don't need an extra few bucks. I also don't need to be a cash cow for people who can easily rob me (which happens to be every person on my rivals list as it is for most people).
Making well over a billion a day has it's benefits. Not having to collect anything you don't want to is just one of them.
