<i>&gt;UBI doesn&#x27;t create a disincentive to work, UBI replacing means-tested programs eliminates a disincentive to work.</i><p>UBI has complicated secondary effects.  Some of them can be contradictory.  One who gets welfare would have disincentive to work because of the loss of benefits in today&#x27;s govt programs. UBI may spur some (not all) of them to join the workforce.    However, another scenario is the mass populations of part-time workers earning mininum wage ($7.25) that total less than $11k a year.  That&#x27;s ~1500 hours of lost labor hours for those who are perfectly fine with not making more than UBI&#x27;s $11k.<p>It&#x27;s definitely not as simple as saying, &quot;UBI <i>only</i> creates incentives to work and never any disincentives, and GDP can <i>only go up or stay the same</i> instead of down.&quot;
