"And change we got, but not the good kind."

This raises a bit of red flag, because lots of people migrate with a vague idea of "the grass is greener" without knowing what they're getting into. Since Belgium is not a bad place to live, I'm wondering what it is you're running away from.

And since you put a work/life balance, cheap health insurance and cheap education top of your priorities (all things Belgium already offers) and don't seem to know very much about the US, I wonder why you're not considering the much less complicated and safer option of another EU country? (Also, of all continental European countries, Belgium is probably most like the UK with it's post-industrial similarities.)

What is it that makes you think you and your family be happy in the US?

I'm getting a strong sense you don't really have a clear picture of that, and are just looking to flee to a magical land far away from your current troubles. I live in a place with lots of expats, and that scenario usually doesn't work out well.
