Secondly, I'm genuinely interested in your thoughts here. What if you:
* Lived in the EU
* Being salaried 100k EUR (which is probably around 90th percentile)
* Worked for a _global_ company with a _global_ product deployed on a _global_ market with _global_ competition
And now some of your colleagues are from the US and you:
* have the same responsibilities as they do
* have the same skill-set needed for given position as they do
* have the same impact, or potential for it thereof, as they do
* have to go through the same agony of being and staying among top performers
And yet your US colleagues are salaried 2x-3x as much as you are. Without taking RSUs into a picture because that's a very rare thing to have in European companies.
What are your thoughts about this? Do you attribute this difference solely to the cost of living?
