WOW! Retirement isn't mentioned in the Bible! Really? Hmmmm, ya think maybe that would be because there were not a bazillion people on earth competing for the jobs? Hell, retirement as a concept for the average Joe may only be a century or so old. Social Security...we can thank FDR for that and it was needed because the people in the 1920's made oodles of money and spent every cent they could. Few saved for a rainy day...and when it rained, it was a deluge known as the Great Depression! Social Security was the "bail-out" to help people at least try to keep their heads above water.
If the guy is going to quote Bible stories, isn't there one about Jesus warning people about idolizing money? But why on earth would a billionaire want to believe a story like that is in HIS Bible? Hypocritical much?
