All of this cheer leading about jobs is certainly done with blinders on, as if nothing was going on previously. The fact is the total number of jobs created for each year of Obama's second term was greater than 2017, Trump's first year. Let me re-phrase this: job growth in Trump's first year was less than any year of Obama's second term. Trump's first year was simply a continuation of growth, nothing more. I'm not crediting Obama, rather, as long as the economy is allowed to expand--without the Fed putting an end to it, employment grows, and employment was growing under Trump's first year at rate less than the previous four--there were no policies changes that would impact total employment.
Now, as I have predicted based on the tax cuts, I fully expect this year to be much stronger. He can certainly take credit for any impact this year, as he should also take blame for the significant expansion of the deficit which is the source of that impact.
