So it looks like they'll hire just about anyone

What's the end goal? Have 99% of the American work force under the DHS?

And then what?

If your borders are so tightly controlled, you're going to turn away enough false positives that everything else will crawl to a halt.

That's in an entirely "efficient" scenario.

You're hiring people who are desperate for money, i.e. people who are more likely to accept bribes, which just completely undermines this whole stupid system.

It just seems to me like they're trying to maximise both bureaucracy and immense cruelty. Am I missing something?
