It's because they are actually lonely and unloved and powerless, and also because they have been fed lies about America and their station in it since the moment they could first understand language.
The mental illness occurs when their cognitive dissonance is strained to the breaking point. When someone realizes that they have labored their whole life, possibly at significant risk to life and limb, for the primary benefit of other people, who do not even return a minimum level of respect, a psychic pseudopod of rage reaches out, questing, for someone or something to blame.
And it usually lands somewhere that is merely close, rather than deserving. They do not understand why their life has been considered disposable, and become determined to make their mark--even if it is to be a scorch mark or track mark--on the world. We are likely already familiar with some common modes of midlife crisis: buy a motorcycle, buy a sports car, buy a boat, get really into one's religion, volunteer for some charity, go back to school, etc. It may well be that when those sorts of outlets are financially unavailable, then "buy a gun, write a manifesto, and start the revolution" is one of the few that remain within reach. Or it may be that they just preferred that one from the start.
Perhaps Switzerland is better at making people feel important, and is not exploitative to a point far beyond the breaking point?
