There is also a hub effect aside from pay. Shannen has all the electronics companies because it is a huge where you can buy anything. A hub can happen randomly outside of policy, like a crystal growing in solution (and it can also be triggered if there isnt one, like dipping a string into super saturated cooled solution).
Remote work is kind of in the process of dissolving the crystallization for software.
I think it’s intrinsic to the models. The U.S. pays top performers better. But the average European has a more-stable lifestyle. The same regulations and labor protections that grant that stability slow down growth, so apart from an internal restructuring it’s tough to see the situation changing.
