Boeing and Airbus

OK, so Airbus are in a lot of financial trouble right now and i't's far from certain that they can recover...but I wonder, can Airbus or Boeing be "allowed" to liquidate? If they did we would have a monopoly on the jet airliner market and they're so advanced in the market that another company (Bombardier, Embraer, etc) would never be able to compete against the remaining big one.
