During the Great Depression, my grandfather was a small town sheriff. When many were out of work, he had a job. The same is true for teachers. When he had the cash, others did not. So he bought up a music store, a well drilling business, and several apartments which were foreclosed. Having the cash is the key. If you have cash, you have power. Power to buy what others cannot own. He bought, bought, bought...The KEY is....be debt free, have as much cash as possible, and then buy wisely. People will always need basics.
