Do trucks with PR cause more accidents than citizens? Do you have a source for your accusation here, or are you just making it up?
I give a fuck. Why have immigrants at all if we aren't benefitting from them. We picked him ahead of others for a reason, who's to say the person we replace him with won't be worse?
