As I noted in another post, ORMs don't typically distance a programmer that much from relational concepts: they simply hide some of the mechanics. If you want to routinely use JDBC and manually construct objects, feel free - I like having libraries doing some of the heavy lifting. The last sentence of your last para is remarkable. I'd be interested to know why an object (a class instance for class-based OO) is a poor representation of data in a RDBMS. You might as well state that a C struct or a Haskell data type is unsuitable for that purpose. If I want to access structured data in an RDBMS, and I am writing in an OO language (not an uncommon requirement these days), I think I'll use a semblance of an ORM. I'm reluctant to write assembly language to manipulate data...not in 2013. If you had mainly negative experiences with ORMs, Silvio, and I'll take your word for it, then perhaps your colleagues were inept or incompetent or lazy. I've experienced the same problems you described, many times: come to find out that the performance problems were human and needed to be fired.
