I wonder if UBI actually allows the economy to become more efficient. It could be the case that an abusive employer would be more severely punished by the labor market if the economic cost to the worker is diminished by a UBI (i.e. My boss is a jerk, I'm just going to quit and find an employer that treats me better). I would assume then that satisfied employees, with good employers, would then be more productive than their dissatisfied counterparts.
It also seems reasonable to assume that workers would also be more likely to create new businesses entirely if the personal financial risks associated with doing so were diminished by a UBI.
