&gt;<i>because grocery stores start having a hard time finding employees willing to do the menial labor required to keep a grocery store running.</i><p>You are over-estimating the value of the income.  People won&#x27;t be &quot;livin&#x27; large&quot; on the basic income.  The intention is to keep people out of abject poverty.  I&#x27;d even argue it would be <i>easier</i> to find people willing to work part-time at places like grocery stores to supplement their income.
