Possibly, but I'm not so sure.
Firstly, my premise was that this isn't the case if inflation stays constant, which means that this process has been going on at the same rate for some time.
So why if this has been going on for some time, and you are loaning me money, am I able to get the better of you? Why won't you charge me a higher rate?
You have seen this process going on at the same rate for some time, and so have I. You could charge me a higher rate, and I would be willing to pay it because we can both see the past ... why am I able to take advantage of you?
