It was typical of Joe Biden’s presidency that, when faced with a difficult problem, he would take the cynical approach of finding a scapegoat to blame while making a promise he never intended to keep. His response to the housing affordability crisis last year was a textbook case: Blame “rent-gouging” landlords and greedy realtors, make the false promise that his administration would build 2 million new homes via more deficit spending, and hope nobody asks questions — a safe bet, considering the incurious media that surrounded him.
