Social engineering by government always ends in disaster. Social engineering occurs when government passes laws and regulations that force citizens to behave the way government thinks they should behave. Prohibition is a great example of social engineering. In 1919, government decided that its citizens should not drink “intoxicating liquors.” This “government-knows-best” idea produced more than a decade of lawlessness far worse than citizen intoxication. Prohibition was repealed in 1933.
