We do not live in a post-scarcity world, and to say that we do shows a failure to understand the economic concept of scarcity.<p>If goods aren&#x27;t scarce, they have no opportunity cost -- anyone in such a society could get as much, e.g., filet mignon as they want without sacrificing their ability to get quality healthcare, education, or consumer electronics.<p>Greater overall and per capita productivity isn&#x27;t, and doesn&#x27;t even approximate, post-scarcity conditions.<p>If we lived in a post-scarcity economy, &quot;You Need A Budget&quot; would fail, because you wouldn&#x27;t.
