Our local college is a missionary college where both my sons was graduated from, the students come from Africa and get a free 5 year college education. They take back with them the knowledge to build in their own land, or to educate their countrymen, or provide health care for the poor there; it would cost 17,000 a year. This is what I paid for each of my sons. Many times, they stay in our country using the education for their personal gain, never returning to help their own country or countrymen. That is a tremendous loss. There is so much poverty in our country, too.
I applaud your son in his effort it is commendable.
