I like that idea. I also think there is always an element of chance. Sometimes looking back it's easy to think there was some special sauce - Britain was special etc, but sometimes it is a large part random chance. This is particularly the case for something like the Industrial revolution where there is a snowball effect - as you optimise the process at one point the shifting economics cascade ( something that was expensive is now cheap, that cheap thing can now be used in places it couldn't before ).
