I&#x27;m guessing the number would be a fair bit lower when you subtract the savings from abolishing the existing unemployment welfare system (and the cost of administering it).<p>And, in theory, those previously on &#x27;tapering welfare&#x27; now face less of a disincentive to work, so there&#x27;d be a bump in pretty much any tax revenue base correlated with GDP (i.e. almost all of them).<p>EDIT: Just to give you a sense of what I mean about EMTRs, here&#x27;s a chart from Australia&#x27;s most recent tax system review -&gt; <a href="http:&#x2F;&#x2F;i.imgur.com&#x2F;jhRYXiB.png?1" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;jhRYXiB.png?1</a> . The interaction of the tax and welfare system means low income earners face an effective marginal tax rate of almost 80% at certain points of the income range (mostly due to payment tapering).
