In the last 26 months of Barack Obama's presidency, manufacturing added 96,000 new jobs. This was an 0.8% growth of his presidency.
In the first 26 months of Donald Trump, manufacturing added 497,000 new jobs. This was a 399% growth of his presidency.
These simple numbers show a hockey curve type ramp-up of jobs from Obama to Trump. It shows that Trumps pro-economic type growth has done well to grow the manufacturing economy.
