So the industrial revolution that was taking place in Great Britain? Would THAT not have happened if western expansion hadn't taken place? Your premise is deeply flawed. The industrial revolution was taking place in the late 1700's. At the time only 5% of the American population lived west of the Appalachian mountains! Western expansion was NOT the engine driving the American economy.
The British Industrial Revolution was taking place then. It wasn't until the last half of the 1800s that the US had it's real heavy Industrial Revolution and that was due to the introduction of the Rails to get the raw resources from the west to the east. You keep trying to present cracked history.
And in 1793, I have an ancestor that was living west of the Appalachians. My Indian ancestor have yet to even have crossed over yet being from what was then known as North Carolina. But my White Ancestor crossed. And so did hundreds of others. What was driving the American Economy was agricultural mostly. America exported raw materials to Europe where they were in the process of their own industrial revolution. It was the Railroad that brought the US it's own industrial revolution and heavy expansion. So the Expansion did come first so that did drive the industrial revolution. But one without the other would not have provided a stable situation. The East needed those raw materials and agriculture products that the west (meaning west of the ohio river) had to offer in order to start the Industrial Revolution of the last half of the 1800s. And it was Railroad and one Canal that made it possible.
Stay focused here. If you wish to discuss Europe, discuss it with a European. He knows a hell of a lot more about European History than either of us do.
