That being said, you can find work pretty much under any president. You can't go blaming a President for not doing something. Sometimes you have to get off your duff and go find something. But, we are now paying more people not to work. That is an issue.
His blockades must have been pretty weak. He's created twice as many net jobs in 7 years as both Bush's in their combined 12 years. And he's got another year to add to that.
