It worked out for us, but I would be peddling bad advice if I didn't add that I don't recommend doing it without a substantial financial backstop already in place.
After a certain income threshold, yes. The income threshold is actually quite high: 103K of income earned abroad per person in a family is exempt from US taxation, which is a substantial savings.
I'm not comfortable disclosing my personal situation in any greater detail in public -- but I'm happy to chat about it over email if you are interested!
