if you can give me one articulate reason as to why we are worth that much less than "A" scalers then I would be interested to here it.
Because BA think that's what you're worth - and the fact that people are still applying shows the market is seemingly prepared to accept it.
I don't think you'll find a single current BA pilot who likes that as it inevitably puts pressure on those on better rates.
Let me paraphrase your statement and return it to you.
If you can give me one articulate reason as to how current "A" scalers could retain those rates for all future joiners, then I would be interested to hear it.
