Libertarians resemble at times the old British Empire. They harp on economic issues such as fractional reserve banking, which no matter how legitimate these complaints might be, they miss the political mark entirely. The British granted the American colonists scores of concessions and were then flabbergasted when the Americans demanded more. They would later make the same mistake with the Irish: the British regularly overestimated the importance of economic issues and neglected identitarian issues. Libertarians will likewise have to learn that the tribe is stronger than the purse.

Blood is thicker than water. Children are more important than GDP. Go and raise some.
