In that wonderful 20-20 hindsight, I wish I'd worked summers at Home Depot in high school, back when it was mostly a local chain. They gave every employee stock options when they first went public, and there are quite a few folks who are retired millionaires in their 30s and 40s because they stocked shelves or drove a truck 20-odd years ago.
I worked at a Lowes warehouse in North MS in 1980. I never would have imagined it being such a large chain as it is today. It was a rather small Southeastern chain then.
