Our current government here in the UK is doing this at the moment. They even revoked a university's license to accept foreign students on a technicality. We make a fortune out of foreign students and with our demographics need them far more than the US, but according to the Daily Mail reading grey brigade if we packed them all off home, all our troubles would be over. Because simplistic, sweeping, poorly thought out solutions to deep rooted cultural and economic issues always work out so well.
It wasn't a technicality. While the response may have been disproportionate, we're talking about brazen corruption from LMU; I have very little sympathy for them.
That 'technicality'(1) was the universities lack of effective checks on students right to be in the UK, which they had 6 months to fix.
I don't disagree that foreign students bring a lot to this country, and that the handling of this thing by the government was extremely poor (2), but you're conflating two different issues in order to make a point about the Daily Mail.
It seems like you're guilty of the same simplistic arguments.
