<i>&quot;Pegging the UBI to the consumer price index could possibly help as well.&quot;</i><p>Don&#x27;t do this!  If we set the UBI unsustainably high, that will probably be reflected in a rise in prices.  In that case, we <i>want</i> the real value of the UBI to fall, reducing that pressure.<p><i>&quot;Or segregating luxury items outside of UBI credits.&quot;</i><p>Also don&#x27;t do this.  If there are fewer things competing for my UBI-tagged dollars, then we&#x27;ll be needlessly driving up the prices of acceptable things.
