The story writes itself.
Because Democrats care about workers, their policies generally support job growth...thus the creation of 99 Million jobs in 51 years of Democratic Presidencies since 1921.
Republicans care about rich people and so their policies support cost cutting, union busting, part-time employment and exporting American jobs. So Republican presidents, in their 52 years of control of the White House since 1921 have only produced 33.2 million jobs.
Economists (dire prognosticators that they are) say that this differential is random, but 103 years of data says something very different. So much so that even Donald Trump, before he became a born again and again would-be dictator, famously (in 2004), said, “It just seems that the economy does better under Democrats.”
