I saw on TV that there are now microcredit institutions that lend funds to the poor at 100% interest. I lend to Kiva because the recipients get the entire loan without interest. It's a pleasure to give money to Kiva because they do not exploit the poor.
I hastened my retirement so that I could read, read, read. Learninng more and more about the world I have developed a strong interest in helping disadvantaged people.
