> Though, if you're idealistic enough to think the UBI is a prospect soon realizable, I wonder why you're advocating minimum wage increases over say, stronger collective bargaining?

Why not both? Seriously I am very much in favour of e.g. working time restrictions, but "union" is a dirty word in the US (indeed you carefully avoided saying it), so I don't think advocating stronger collective bargaining rights would help me achieve my policy goals.
