There is no &quot;perfect system&quot; in the same way that there is no &quot;perfect algorithm&quot;, unless you can define the goal.<p>What is the best sorting algorithm?  Is it the one that sorts a random list in the shortest time?  Or the one that uses the least memory?  Most likely we&#x27;ll pick by balancing a few important metrics, which leaves us with &quot;optimal&quot;.  Far from perfect.<p>If we&#x27;re discussing Capitalism vs Socialism, instead of criticizing the opposition for ignorance (like every comment below the WashPo story), let&#x27;s accept that different groups are optimizing for different goals.  And there are so many competing objectives: efficient distribution of wealth, national economic growth, safety net for unlucky&#x2F;disadvantaged, protecting shared resources (environment), etc etc etc.
