But whatever forces into a branch of trade of which the returns are slower and more distant than those of the greater part of other trades, a greater proportion of the capital of any country than what of its own accord would go to that branch, necessarily renders the whole quantity of productive labour annually maintained there, the whole annual produce of the land and labour of that country, less than they otherwise would be. It keeps down the revenue of the inhabitants of that country below what it would naturally rise to, and thereby diminishes their power of accumulation. It not only hinders, at all times, their capital from maintaining so great a quantity of productive labour as it would otherwise maintain, but it hinders it from increasing so fast as it would otherwise increase, and consequently from maintaining a still greater quantity of productive labour.
