Can't you just stop buying airplanes from them? Edit: Do the downvoters also want to throw the executives in jail for life?
Ah yes, the magical invisible hand of the market will solve this. Now when going on holidays, I need to be factor in the safety standards of the planes that will be servicing my route. Or you know, get a government regulator to regulate airplane manufactures like normal countries.
Ps if you're flying in a developed nation you probably can rely on regulators to regulate airlines, if you're flying in less developed nations, probably not so much.
