I don’t disagree with any of those and I said that I don’t hold Obama blameless. But again, I hold the Republicans in power to be a large source of the problems as they have been pushing trickle down economics for over 30 years and it does not work. But that’s their only answer.
Regarding a couple of your stats — $18k minus $12k is $6k, not $8–10k. Regardless of that fact, studies have suggested that the rise would have been greater without the ACA: “ These increased costs for employers and employees alike may seem steep — up around 50% over the past eight years — but they could have risen far higher had the Affordable Care Act never passed. The Kaiser study shows that average family premiums rose 20% from 2011 to 2016. That rate of increase is actually much lower than the previous five years (up 31% from 2006 to 2011) and the five years before that (up 63% from 2001 to 2006).” http://time.com/money/4503325/obama-health-care-costs-obamacare/
And labor participation rate is NOT equal to “true unemployment” rate. There are many reasons why the labor participation rate has gone up, including, yes people have gotten discouraged and stopped looking for a job, but also people going back to school, retiring, etc. About 15MM jobs have been created since the end of the recession, and # of jobs under Obama is about 10.3MM, So # of jobs was certainly better under Obama than Bush http://money.cnn.com/2016/11/04/news/economy/jobs-under-obama/.
I could comment on all of those points but I don’t have the time. Like I said before, Obama isn’t without blame. But he took over the country that was in a world of hurt, and while there are people out there not doing well, overall the country is in better shape than when he started.
