&gt; Money comes from taxpayers.<p>Money comes from the government that issues it, actually. <i>Government operating funds</i> come from a variety of sources, but largely, it is true, tax payments.<p>&gt; What if a majority of taxpayers decide they&#x27;d rather not work?<p>If you mean &quot;decide not to take actions that create taxable income&quot; (UBI -- and government in general as increasing automation eats traditional employment -- only works with ending preferential tax treatment of capital income, so that &quot;work&quot; and &quot;create taxable income&quot; become even less the same than they are currently), then either:<p>(1) If UBI is variable in quantity based on distributing proceeds of a dedicated tax stream among the qualified recipients (i.e., the citizenry at large), then the UBI amount drops, and that decision because less attractive, leading to more of those able to earn taxable income in addition to the UBI choosing to do so; this is a self-limiting negative feedback loop.<p>(2) If UBI is <i>not</i> variable, and is fixed in nominal value, the reduction in <i>production</i> relative to the supply of money in consumer hands caused by that decision leads to increased inflation, reducing the <i>real value</i> of UBI, leading to the same results as in #1. Again, a self-limiting negative feedback loop.<p>(3) If UBI is inflation-indexed, then you have a positive feedback loop that blows up the system. So, don&#x27;t do that.
