Which of the following statements is NOT a reason why countries other than England had difficulty industrializing

I know France in particular had a hard time securing coal, which is one of the reasons they would come to exploit Germany so badly after the first World War. I also know that Britain made the export of textile machinery illegal until the mid 1840s. Regarding feudal agriculture, well, well landlords of France certainly treated the peasants as serfs well into the 18th c., which led of course to the French Revolution.

Their populations were too small to support a large enough workforce.
