Do economists care at all about job creation?

Yes, the primary reason why economists care about recessions is unemployment. If GDP simply declined 5% or even 10%, that wouldn't be a big deal. That's only a few years of economic growth: a recession in 2008 would be like traveling back in time to 2005.

However, rather than making everyone 5% worse off, recessions sharply affect a few people (the unemployed), while the lives of everyone else remains pretty much unchanged. For this reason, the majority of economists support policies which decrease the unemployment rate.

While economists care about reducing the unemployment rate, they don't care about "job creation" as policymakers refer to it. While a policymaker would justify policies like tariffs on the grounds that they create and save jobs, an economist would not. For example, according to Paul Krugman:

It should be possible to emphasize to students that the level of employment is a macroeconomic issue, depending in the short run on aggregate demand and depending in the long run on the natural rate of unemployment, with microeconomic policies like tariffs having little net effect. Trade policy should be debated in terms of its impact on efficiency, not in terms of phony numbers about jobs created or lost.

No. Economists care about reporting the economy, trends in the economy and how decisions by companies and politicians could effect the economy.

You can use this information to create more job but economists are just a strong tool. They aren't the ones doing the actual work
