alt Hacker NewsI'm not an economist, but I have heard that there's an argument to be made the easy firing also makes it so that it's easier to hire too, so it creates more jobs.
That's one of those things that sounds like bullshit, so I don't know that I believe it, but that's what I've heard anyway.
The other part is that at-will goes both ways: you can just walk out of a bad job with no legal repercussions. Not always the best idea due for social/professional ones, though.
