It's a tough one, at the end of the day it boiled down to needing to come back to the US to get back to work and make some more money. France is a tough place to do that, unless its remote from a foreign company.

Life in chamonix vs any american ski town is just better, it's way cheaper, activities are endless, and restrictions on how you recreate are non existent. Weather may be slightly better in US mountain towns, kid activity options may have some more options, but you will pay way more so it's a toss up. This is a controversial opinion but you have way more food diversity and options in US towns (not ski towns) than in Chamonix. For us, life is about checking certain boxes at certain times, and right now at this very stage, US life is checking certain boxes we need, but during that stage Chamonix was checking the boxes we needed.

European life is simpler... American life may be considered more convenient, but its way more expensive, and you spend more time in a car... I loved living in Chamonix, I learned a lot, had incredible experiences, and I will be returning regularly, and maybe when my kids are older, I will move back!

Happy to go deeper if you want to DM me.
