Having a single (or even a group) of people to pin this on is very attractive because it gives a clear defined target to oppose. The problem is, the more you study it, the more you see the problem continues and is reproduced regardless of who is in "control" and what their intentions are (good or bad).
That's why the problem is systemic.
I might be able to agree with this except for the fact that:
It is a LOT easier to destroy a thing than it is to build it back up AFTER it's been ruined. And the more damage that's done ... the more that needs to be done to make it right again.
In the case of the economy ... if you look over the past 50 years, Republicans have had many, many more years in control of our government implementing their destructive "benefit the rich" economic policies than Democrats have had to try to implement policies to 'right the ship' after it's been sunk!!
Now, of course, BOTH Parties (i.e., politicians in general) have some blame for the reason we are where we (economically) are right now. I don't think that can be denied. But when you have ONE side so much more bent on destruction of the economy and the middle-class while at the same time favoring Wall Street and the rich ... and that side has been given MORE time to put that destruction into action and MORE control to do so than the OTHER side ... I don't see how you can fairly place the blame equally all around.
