I expect to be all tested and ready to go well before the time the date arrives. If there are problems, my guess is they may surface in some of those enormous systems that are interdependent and interlinked, such as the telephone system and maybe parts of the banking system. There will also almost certainly be many problems with state and federal agencies, but none so serious as to bring everything to a halt. Putting aside politics, there are some economic observations that I think are pertinent as we experience Presidential apologies for his less than honest personal behavior and untruthful answers. We have all derived wealth from an expanding free market.
Free markets are dependent upon trust for efficient operation.
Indeed, it can be argued that markets ultimately collapse where people cannot be relied upon to keep their word and honor contracts, verbal or written. The Dutch would pay you back, the Spanish Monarchy regularly repudiated its debt. The Dutch honored contracts, and, in those days, the Spanish did not. Much of the problem in Asia today, as well as Russia and other Eastern European countries, is that folks there cannot be relied upon to honor contracts. Officials want bribes, debts are created and then undercut by devaluation, political and ethnic opponents are brutalized and the old Protestant Dutch rules of honesty and fair play, the rules upon which our economy were founded, are widely ignored.
