The world is complex and ever-dynamic. I agree that some of these old economic theories can be applied to solve some present economic problems but cannot handle all of them. New challenges should be handled creatively and innovatively based on the peculiarity of such problems. The problem with economists is that they want to apply the same economic principle to a new problem expecting a positive result.

If you check the history of most of these economic meltdowns that have occurred over the years you will discover that greed is behind more of them. Some of these major banks went bankrupt because of the financial recklessness of the managers. Some of them issued unsecured loans to businesses they have a personal interest in. An example is the economic problem in China which is caused by the slump of the real estate industry.  The problem started when banks were giving loans recklessly to real estate companies without considering the consequences. I will be right if I say economists are the problem and they also claim to be the solution. This is why they will always reject Bitcoin because it will reduce the extent of their influence and malpractice.
