Of all of these companies, Amazon will be by far the most disruptive to these other countries. The key difference here is that Amazon slowly built and perfected their model here in the USA, allowing domestic competitors time to adapt to the ever growing efficiency and disruption brought by Amazon. Amazon can then take this perfected model and drop it like a bomb in other countries. (Not that they haven't already done so in certain segments, but wait until Amazon Fresh hits some of these countries) Eventually, even the US is going to face a HUGE disruption with the advent of self-driving trucks. As bad as that will be in the US, it will be worse in Europe, where wages for truckers are much higher and will incentivize replacement. I predict that Europe will be much, much later to approve self-driving vehicles than the US will for these reasons.
