Putting all the blame or credit on one leader is incorrect. You have to look at what specific policies they drove and actually implemented and what the effects were.
Should Clinton get all the credit for the 90’s? Absolutely not. Clinton should send thank-you’s to the 90’s Republicans who prevented him from implementing many of his policies. He should also thank the PC business / Internet boom which drove the phenomenal growth of the decade. He benefited from the Internet bubble and the massive productivity gains and business growth, while Bush was impacted negatively by the bursting of the Internet bubble. Clinton didn’t create the technology boom and Bush didn’t burst the bubble, but the stats of both are impacted by them.
And the problems at the end of Bush’s term were largely from the race-baiting housing bubble driven by Democrats — the very thing they are doing again!. Sadly, they were able to exploit people’s ignorance on the matter, with the help of the Democrats and their media allies who ignored or lied about the root causes. That not only led to us getting Obama, but they pretended that a President couldn’t make real changes in one term. Ugh.
