> I'm sure if they didn't keep the prices somewhat similar, you would have a bunch of people in Europe selling RAM to Americans.

I was just about to edit my response to the GP to say the same thing. Let's explore this hypothetical situation a bit further.

Suppose there was a DRAM manufacturer named "Acme DRAM" which decided to have a separate pricing schedule for the EU reflecting the lack of insane US tariffs.

Some enterprising entrepreneur in the EU would establish a company in the country having the least US tariffs and resell Acme DRAM to US companies. Surely this would make money hand-over-fist.

Problem is, the US DoJ does not look kindly on this kind of enterprise:

  DOJ also has demonstrated a growing willingness to pursue 
  criminal charges against companies and individuals involved 
  in customs fraud schemes such as the purposeful 
  misclassification of goods, falsifying country-of-origin 
  declarations, and intentionally shipping goods through 
  low-tariff countries. Importers of goods into the U.S. 
  should expect criminal enforcement to accelerate in the 
  coming months and years.[0]

This would then put Acme DRAM in the crosshairs of an already vindictive and erratic US administration, likely to not only hammer the entrepreneur (see above) but to also include tariff ramifications for Acme DRAM as well.

All of this risk in the pursuit of lower profit margins by definition.
