UBI would overhaul the economy, but it's not like that doesn't happen regularly, just not for the benefit of workers. It's got to be studied before being implemented on a wide scale but there's no reason to assume it's not possible.

Obviously if you give $1000 to each person, taxes have to be raised by an average $1000 per person, which sounds really bad as a soundbite. An implementation using negative tax brackets doesn't have this soundbite.
