Plus it is much harder for boeing since it isnt subsidised.
Boeing recieves lots of subsidies.
Around $4 billion from various US states as incentives to build parts of the aircraft there, and another $1.5 billion from the Japanese government because several Japanese companies are partners in the 7E7 program.
Airbus has recieved significantly less than that for the A380, and all in the form of low rate loans that have to be paid back.
Boeing also gets part of their R&D work done by NASA, courtesy of the US taxpayers, another subsidy.
