Retraining for what? Another comment mentioned FDR and infrastructure projects, but this isn't the 1930's. Even if there were a massive infrastructure project, that's good for at most 5-10 years of employment, and then what? Retraining we can do. However, we can't create massive new job sectors to hire those retrained workers, unless it's make-work government jobs (in which case we'd be better off paying those people a basic income and not removing value from government services by making them more complex and bureaucratic than they need to be).
