Obama failed to fulfill, by far, both the promises he made when he run for president AND the hopes/illusions nurtured by those who voted for him but holding him accountant for all the misery that befell on the regular Joe is a little too much.
This kind of mistakes is very costly. Those who forget that the daily actions of each and everyone of us aggregate into our common destiny tend to believe that we might change our fortune simply by changing the leader.
History has proven, time and again, that we’ll keep making the same mistake until we’ll eventually understand what went wrong. And start doing ourselves what needs to be done instead of looking up to somebody above us to direct our actions.
