In my family it's already happening. I am one of three siblings all of us late 20s early 30s, grew up middle class in SoCal. My brother went to college in Germany because it was more affordable than attending a 4 year university in our home state. He's been in Germany now for eight years. He graduated, got a job, got married. He and his wife are never coming back. His POV is that the things he needs to live (healthcare, shelter) and the things he needs to work and have a family life (childcare, mat/pat leave, safe and timely transit to jobs, more job security) are affordable/attainable whereas those things are expensive and increasingly out of reach in the USA. He jokes that our TVs and material goods are cheaper, but you can't live in a TV. My sister and I have both weighed moving to Europe. The cut in paper salary vs. cost of living seems to be heavily in Europe's favor once you have 2-3 kids. When we get to that point, we may make the move too. We have an advantage that my sister and I received Italian citizenship through a great grandmother in 2020, and my brother received his Italian citizenship this year so moving and staying in Europe long-term will be simpler in that respect for us.
