I apologize if the hemshech wasn't clear enough, I was equating savings of 2.5% CB from a CC to savings of rent from a yoresh'd house. On what halachic basis is CB/Pts considered a rebate? (And don't tell me because that's how you feel inside.)
Let us take your logic a little bit further. You go to a store and buy something for $98. You give a $100 bill, and they give you $2 back. Do you have to give Maser on the $2. I assume that you agree not.
My dictionary explains the word rebate as follows: "A return of part of the original payment for some service or merchandise".
When you get get points or miles, you are getting something back, in lieu of your original payment.
When you live in a house for free, you are not getting anything at all. You are just avoiding payment.
You yourself wrote that "The Shevet Halevi speaks of inheritance of property because those who receive such a present do not have the means to separate such a great sum, as is many times the case with miles." I of course hear that one is not expected to pay out $50k in maaser upon being yoresh a house, but I am not sure how you are extending this to a monthly savings of rent.
The Shevet Halevi required the above reason to explain why you dont give Maser for the gift itself. As to the monthly savings of rent, that was not even a discussion, which is why I believe the Shevet Halevi does not even bother to address it.
To put it this way: Are you suggesting that someone who bought a house and paid it off still should be paying Maaser for the money that he saves in not paying rent?
Anyway, I think it's silly for most of us to try to be paskening anything here at all.
Agreed.
the only thing that should be discussed are potential svaras/positions on the metziyus on miles.
That is what we are doing.
Shall we start another thread on shchita perhaps?
I am game.
