“The most important possession of a country is its population. If this is maintained in health and vigour everything else will follow; if this is allowed to decline nothing, not even great riches, can save the country from eventual ruin.”

“The glory of saving a country doesn't mean having to use the measures that contributed to its ruin!”

“Further, an excess of legislation defeats its own ends. It makes the whole population criminals, and turns them all into police and police spies. The moral health of such a people is ruined for ever; only revolution can save it.”

“On the other hand, if you're too delusionally optimistic, you'll be unbearable. You'll refuse to save money or make backup plans. You'll invade foreign countries and expect to be greeted as liberators. Like everything else in health, you need balance.”

“Foreign aid might be defined as a transfer from poor people in rich countries to rich people in poor countries.”

“Colonialism hardly ever exploits the whole of a country. It contents itself with bringing to light the natural resources, which it extracts, and exports to meet the needs of the mother country's industries, thereby allowing certain sectors of the colony to become relatively rich. But the rest of the colony follows its path of under-development and poverty, or at all events sinks into it more deeply.”
