>The money is pretty easy to judge, and as far as I can tell, total comp is a good 'honest signal' that I'm going to be treated in other ways. How much money they offer is a better indicator that I'll be treated well, in my experience, than anything anyone can say at an interview.

Eh, not in my experience. I've often seen it as an excuse to treat people poorly. As in "You're being paid a lot to put up with BS" and "Highly compensated shouldn't have excuses or whine." It also seems to correlate well with their trying to solve all legitimate work headaches with money.
