Not a rare opinion from those lucky enough, rich enough or sufficiently qualified to be here legally. I'm sure those folk feel more threatened than we do, on more than one level. It'd make more sense to tackle the root of the problem, which is an unpleasantly human mixture of greed, envy and ambition which leads to the conditions that force, otherwise contented people for the most part, to witness the destruction of every aspect of their normal lives...But that's never going to happen. Capitalism has much to answer for and every financial incentive to ignore it.
