I'd say weak wage growth for the working class over three decades is catching up with the US consumer driven economy. Of course that's easy for me to say as most economist have stated the same thing.
So we have had the very un-American practice of shipping jobs offshore.
Many companies are waving a carrot in front of potential illegal immigrants who happily accept low wage jobs.
Automation is replacing workers.
The rejection of an increase of the minimum wage (70% of Americans support this).
The rejection of the equal pay for women (over 60% of Americans support this).
All these items listed are killing the working middle class and working poor class which makes it really tough for these folks to contribute to the economy.
I remember when the recovery was really dragging a group of CEOs were asked "why is the economy dragging"? The overwhelming response was "people aren't spending". Which makes sense, as people watch their expendable income dwindle and dwindle. We have the private sector doing nothing about wages, despite very good profits and we have our representatives doing nothing about it because of polarized ideological politics.
It's no wonder the US is slipping while other countries who have middle class getting stronger catch up and in some cases passing the US.
As usual you add a few talking points and unsubstantiated assertions.
I dont recall a group of CEOs saying that. I do recall them fingering regulatory and tax uncertainty with the Obama administration.
The economy is going downhill thanks to Obama's policies. Here.
Now I see why you ask so many questions about graphs and charts. You seem to think the graph you posted is supposed to mean something?

Thanks for confirming what I already knew,,,you are clueless. Graph's typically have data running vertically and horizontally as reference points to the line's progress left to right. Sometimes bars are used, again with data references vertically and horizontally. That graph you posted means absolutely nothing without data references.
Oh, read this;

Now I know you might have a difficult time because the above article isn't your everyday, every hour and every minute talking points, but go ahead and at least try. Maybe you can digest information that isn't spoon fed to you?
Finally, do I think Obama shares some blame? Of course I do, along with Congress (that includes both do-nothing parties) and the private sector.
