Current politics means a jobs guarantee would tank economic productivity.

But there's a very good chance that the politics of the modern day would turn a job guarantee into something very different from the New Deal -- and make it much less beneficial for the economy.

First, there's the question of whether people could be fired from the new program. It's easy to imagine good reasons to fire someone from a government job -- starting fights, for example, engaging in criminal activities or simply refusing to work. Even if a job guarantee allowed workers to be fired for egregious offenses, there would doubtless be intense public scrutiny of firing decisions, especially on social media. That would put immense pressure on the administrators of the federal jobs program to avoid firing even those who deserved to be fired.

The likely results would be a drop in productivity as some people realized they didn't have to work to collect paychecks, increased resentment among those who felt morally obligated to put in a hard day's labor, and disruption of the workplace due to toleration of disruptive or criminal behavior that would never be permitted at private companies.
