I've been contemplating switching to cash because it's easier to spend less, even when accounting for cash back, air miles, etc. I think this is why banks and businesses are pushing so strongly for cash less transactions only. People simply spend more this way because they are less aware of their spending. And if people use credit and don't pay things off every month, then there's interest too on top of the extra spending. Of course this is worth spending millions lobbying for, enacting, and enforcing. People are the only ones losing out on their money and privacy while companies win.
