To be truthful, it yopu had 7 kids and made $43K per year, you probably would pay very little if any income tax. However you WOULD pay SS and Mediscare tax of about $3000.
But at this point my heart goes out to the children. I cannot imagine how abandoned and forgotten they must have felt in a country thousands of miles from home and completely without hope. Just reading the story makes me want to grab them all and pull them close and tell them that it is all over and they will be taken care of now by people who really do love them.
Thank God that He sent those missionaries to that orphanage to rescue those children.
