What are the strategies here?

Possibly a more extreme one, but I got citizenship elsewhere.

Australia taxes more, make no mistake, and the earning potential is less. Living in Australia though was the biggest improvement to quality life I've ever had. I've lived in San Diego, Los Angeles, San Jose, SF, Portland, Seattle, Honolulu, and Sydney, and Sydney is #1 by such a large margin it shocked me.

My taxes went to funding public transportation that works. They funded government services like ServiceNSW that made me shocked how bad the DMV experiences were in the states. There's nationalized healthcare where I no longer had to worry if my friends could afford healthcare. The government has plenty of its own issues, but none of them felt as on the edge of the event horizon as US politics do.

I felt safe in Australia. With how things are again, I'm so glad I hold a passport with a kangaroo.

Depends on your set of values.
