What's a disproportionate number? I hope you're leaning toward a small number because I somehow doubt that you're going to be able to provide reliable sources for your assertion. People falling off of the roles of UI doesn't mean they got a job. Some go to school and some find less legitimate ways to try and support their family. When you go to jail, you don't get on the UI roles either. Also people getting a job doesn't mean they have a job sufficient to feed their family or one that is well met with their education. It could mean that they went from being pharmacy techs to pizza slingers.
While you're correct there are no guarantees in life that doesn't make its ok for rich lawyers disconnected from the populace they are intended to serve to suddenly yank the carpet out from under a bunch of unfortunate people. Not everyone on UI are mooches, some have just fallen on hard times and need a hand. There's no reason for such poverty in a country as rich as ours, especially since so many of the people yanking the supports from the bridge purport to follow the teachings of Christ at a time of year when we're all forced to endure their inane bullshit.
