I didn't say you were naive. You said you were naive, or that maybe you were naive.
Everybody and their brother sponsors credit cards these days: banks, CU's, fraternal organizations, retailers, foundations and on and on. It so happens my most used card is sponsored by the CU at the company I retired from. That's because their customer service is best. They answer the phone when I call. But I'm not nostalgic over it.
I don't trust credit card companies or want to bother to understand their terms in any depth, so I simply maximize their benefit to me on my terms and count on them for very little. DW and I use a CC for most all day to day expenditures and sometimes run up some significant balances when traveling. But, in the 37 years we've had CC's, we've never failed to pay the monthly bill and have never incurred a finance charge. It's convenient, we get a little float on the money, they give us points good for trinkets and it costs me nothing. That's all the involvement I want.
I don't count on them as my emergency fund or my banker. Just a necessary evil in today's world that can be used to advantage if you don't go beyond charge this month - pay next month.
If you say you're not naive, I'd say "Yes."
