You are confusing cause and effect. It wasn't mainline votes that created the RJ business; it was technology (50-seat planes powered by efficient engines) and the presence of cheap labor that created the business model. RJ existed first, the the RJ business. You want to blame somebody--go with BBD, Embraer and the engine designers plus the thousands of people willing to work for RJ wages. If you are a RJ pilot, the mirror, perhaps.
