“A country with secure property rights, scientific inquiry and technological innovation will become richer. But, since division of labour is limited by the size of the market, it will also benefit from trade, not just in goods and services, but in ideas, capital and people. The smaller a country is, the greater the benefits. Trade is far cheaper than empire, just as internal development is a less costly route to prosperity than plunder. This was the heart of Angell's argument.”
