It means:
"If you love your children, you'll hit the road. The quicker, the better."
I am one of those white South Africans who left, six years ago, and for the reasons mentioned. Getting prevented from reaching the top in big companies despite being well-qualified, and getting shot at in our own home is no way to raise my children. I hope they were young enough when we arrived in the USA so that they will see themselves as Americans.
Bless your heart and your family. Welcome to America.
Thanks.
So glad you made it over. I wish we could have more people in your boat in the U.S.
