Could you imagine what Trump's approval rating would be if he enjoyed the same lovefest that Obama did for 8 years, where over 47% of all the articles on him were positive?
With regards to the economy, it is booming in spite of what Obama thinks or says.
3.7% unemployment with the LFPR on the rise, with the most people ever employed in US history. Wages increased 3.1% for the year as of last month.
I think America has always been great, but it went into an economic hibernation during the later years of Bush and almost the entire Obama Presidency. With regards to jobs, I know that this economy is actually producing full time jobs, where the Obama economy took full time jobs and turned them in to part time jobs, with the loss of benefits, mainly due to the ACA and the increasing healthcare costs.
I think Trump is for bringing back jobs to the American worker. If it is union jobs, then so be it. the revised version of NAFTA is actually geared towards the UAW and they are happy with the improvement. I believe under Obama, a grand total of roughly 800,000 manufacturing jobs were created, where under Trump, through July 2018, over 400,000 manufacturing jobs (the ones that would not be coming back) have been created, which if you work it out, on a like for like basis is 3 times the rate of that under Obama.
