I would venture to guess that some of it may be due to American exceptionalism or better put the belief in it. Until recently optimism has been a pretty big trait among middle class Americans. It was not uncommon to have a conversation with someone and have them say something like it will all work out, or brighter days are ahead, with both parties taking it as an absolute truthful forgone conclusion. As such perception is reality, when people believe that they tend to not allow their mind to venture towards the negative and tend to offer advice that while valuable, is only geared towards the positive outcome. This may in effect reinforce the perception of optimism and exceptionalism. I could be wrong but I would suspect that it is a contributing factor.
