Reasons to be hopeful about the Biden economy. The next few months will be hell in terms of politics, epidemiology and economics. But at some point in 2021 things will start getting better. And there’s good reason to believe that once the good news starts, the improvement in our condition will be much faster and continue much longer than many people expect.

OK, one thing that probably won’t get better is the political scene. Day after day, Republicans — it’s not just Donald Trump — keep demonstrating that they’re worse than you could possibly have imagined, even when you tried to take into account the fact that they’re worse than you could possibly have imagined. One of our two major political parties no longer accepts the legitimacy of elections it loses, which bodes ill for the fate of the Republic.

But on other fronts there’s a clear case for optimism. Science has come to our rescue, big time, with the miraculously fast development of vaccines against the coronavirus. True, the United States is botching the initial rollout, which should surprise nobody. But this is probably just a temporary hitch, especially because in less than three weeks we’ll have a president actually interested in doing his job.

And once we’ve achieved widespread vaccination, the economy will bounce back. The question is, how big will the bounce be?

Our last economic crisis was followed by a sluggish recovery. Employment didn’t return to 2007 levels until 2014; real median household income didn’t regain the lost ground until 2016. And many observers expect a replay of that story, especially if Republicans retain control of the Senate and engage, once again, in economic sabotage under the pretense of being fiscally responsible.
