Haha I kind of see both your points, it kind of does the liberal thing of extending the umbrella of protection from exploitation while pushing exploitation farther to the sidelines. The worst case outcome is that you now have more defenders of the status quo, because they've got it good. Meanwhile the entire economy is still based on war and exploitation, especially of poor workers in other countries.
But then maybe if us workers here had some more breathing room (perhaps not the best choice of words...) we might also have more capacity for solidarity with those exploited workers. Who knows, but it would remedy a lot of immediate problems here anyway.
And all the trials have been very positive, so I'm inclined to give it a shot yeah.
