Why do EU citizens have to pay 42% more for the Moto X style???

Actually I wanted to buy new Moto X style/pure. It is in my opinion a pretty good phone with a good price also. In the US, they will sell it in the 16GB version for 399 (I mean who needs more memory when there is a microSD slot up to 128GB). 399USD are converted 350 euros. In Europe, there will not be the 16GB version, so you are forced to take the 32GB version, which will cost here 500/530 (motor maker). That is 42.857% more than in the US. With the knowledge that you will be completely ripped off as an EU citizen, I'm not going to buy this phone in any case. What do you think about this?
