well, yes in many many cases, but not as a blanket no exceptions absolute rule
I know nothing of catholicism, so can't go into specifics on how they organise themselves, but there are self sufficient self financing churches that do their own thing, don't have shiny silverware, haven't invested in some big leaders hat, cape and pension fund etc etc
I feel myself being dragged into the old arguements of another thread so as fascinating as the whole subject is to me, and as much as I'd genuienly like a proper debate, I'm going to try and resist as we all know where we all stand.
