He who wields the weapon is responsible for the results. Government wields the power of coercion, thus the results of coercion is their responsibility - and the shared responsibility of those that consent to such government. Yes, the lobbyists who abuse the coercive power of government share the blame - but so do you, if you support the existence of this coercive power and their ability to abuse it. If somebody tricks you into shooting yourself in the foot by claiming your foot is a space alien intending to eat you - he is to blame for tricking you, and you are to blame for being an idiot. You can say we should get the world rid of the people who are willing to trick idiots for their own profit, but I say it may be much more practical to try and be idiots less frequently. Because the former is not very likely to happen anytime soon.
