Economic and political differences probably have a lot to do with the price difference, but another factor is size. Based on the overall difference in geographical size, I would absolutely expect higher shipping costs in the US. That SF to LA shopping cost likely subsidizes the cost of shipping from LA to Orlando (far and moderately expensive) and even the cost of shipping LA to rural Wyoming (closer but possibly even more expensive). As a country grows in area, a graph between all points within would increase exponentially. So I'd posit that, similar to the square cube law, shipping costs would grow exponentially with increases in geographical area.
