How could you even suggest this when the "experiment" itself isn't over? While I agree with you no system is perfect, this seems to be the best system we have had ever in the history of mankind. You need to trust the laws of math and that is all that needs to be done. Also, I don't look at things that effect the whole world as an "experiment". These are systems put into place in order to better peoples lives, we surely aren't taking some random stabs at it and hoping it is correct. We do it with the intent it is correct, and if it isn't we will find out soon enough.
