In April 2008 total employed, not seasonally adjusted, hit 145.9 million, which was 48.1% of the US population of 303.38 million.
In April 2017 we're at 153.3 million, 47.4% of the US population of 323.58 million.
If we had employment at the 2008 rate, there would be at least 2.4 million more employed today than there are.
But no, Trump is making America great again, you see.
