“During the Great Depression of the 1930s, President Franklin D. Roosevelt said: ‘The country needs and, unless I mistake its temper, the country demands bold, persistent experimentation. It is common sense to take a method and try it; if it fails, admit it frankly and try another. But above all, try something.’ Whatever the merits or demerits of the particular policies tried, this approach generated uncertainty, which can make investors, consumers and others reluctant to spend money when they cannot form reliable expectations of when or how the government will change the rules that govern the economy, or what the economic consequences of those unpredictable rule changes will be.” – Thomas Sowell
