One of the failures of presidents who preceded Mr. Biden, was to let the revolving door policy of letting private sector executives to join government and set rules that favored the companies they had connections with. This made it harder to tackle the problems of the 2009 global financial crisis triggered by corporate overleveraging and shoddy mortgages. It also left workers and families unprotected, failed to invest in rebuilding American infrastructure, and did not do enough for the middle class. The result was a recovery that failed workers and families- a challenge left for Mr. Biden to tackle and requiring vigilance to avoid missteps such as this one of letting banks and large corporations write the rules they must follow.
