May I ask why you eschew the basically free money that comes from credit card rewards as a responsible credit card user?
Is it really free money? Actual cash ? I've always seen rewards programs advertised in terms of discounts on specific products or services: consumer electronics, cruise vacations, furniture, gift cards, and other things I rarely spend money on. I expect it to be an overstock clearinghouse, something like the old Columbia House record club, where you would page through a catalog of random stuff looking for anything yo…
There are fee free cards that give cash back as statement credits (AMEX Blue iirc). No limitations on what you can spend it on. The Apple Card does 2% cash back which you can just transfer to your bank account.
The Amazon card requires a Prime membership, but gives 5% back on anything bought at Amazon. I bought my last TV using the 5% back I had received.
Then there are top tier cards like the Chase Sapphire or Cap One Venture X that have yearly fees. But, if you take 1+ trips/year they immediately pay for themselves and more (credit for global entry, yearly statement credit for travel that almost equals the yearly fee, lounge entry, etc...). I routinely use points from the Venture X to cover travel expenses like tickets, rentals, hotels, eating out, etc...
