Not true, I personally know several widebody FO's who have been domestic CA's but bid back into the right seat, pay is about a wash but QOL is vastly better.

At SKW, CRJ FO wins vs. EMB CA in every category except pay which is a wash. Unless you need TPIC or live in a Bro-only base, there's no point in doing the EMB upgrade.

Well I guess some folks just have a need to be large and in charge, so it might be better for them to reign in hell...
