Repeating your falsehoods won't make them any more true. To get growth through the Obama administration significantly lower than the past couple of years you have to include the latter part of Bush the Younger's second recession. And yes, large scale economic trends are lagging indicators no matter how much you want to pretend otherwise, (it simply takes time both to enact changes and for those changes to have an impact).
And again: The main limitation over the first half of the past decade was GOP stonewalling on even things like maintaining public infrastructure.
You might also want to look at the real research regarding taxes and the economy: Cutting taxes has very little positive impact, especially cuts that favour the wealthy, (at the top end a $1 tax cut can mean only $0.30 in GDP growth¹, contract with infrastructure spending with direct impacts on the order of $1.50 GDP/$1 spent). Not that I expect you to, given your public demonstration of woeful ignorance².
Another thing you might want to do is to take that time you think things were great for the US economy³ and look at what taxes were back then. It might shock you to learn that today's arguments are pretty much about about "not quite the lowest in living memory" and "the lowest in living memory."
1: Shockingly, the richer you are the less you tend to spend as a fraction of your income.
2: Seriously, increasing taxes on the rich is the exact opposite of a regressive tax policy.
3: A warning about looking prewar: In the latter 19th/early 20th century the US spent most of the time in recession, (the US was not particularly bad off⁴, it was a general problem). Although that was mostly due to the use of deflationary currencies.
4: In fact, the US did better through some of the worst times. Most nations had a single two decade long depression starting in the 1870s, rather than two just under a decade each.
