...and I quote: "Consider the economics of Britain’s calculus. The raw goods to manufactured goods trade with the American colonies was profitable (North America accounted for thirty percent of English exports[15]), but it didn’t compare with the potential for gains in the East. Defending America had gotten expensive, as the Seven Years’ War showed, and the colonists were evidently unhappy to pay for that defense. In contrast, the colonial government in India made substantial revenue from taxes on Indians, and the goods traded, including but hardly limited to spices, were valuable. England was undergoing the agricultural and then the industrial revolutions; a growing market to sell goods was not overseas but right at home. This de-emphasized the market for exports, America, in favor of the source of imports, Asia."
