Time for a story

I've never told this one on the Internet or IRL. But it's true. When I was a young boy I had an elderly relative I shall call Uncle Raul. He was the only person in our extended family who was wealthy. When I asked him about his job he said 'I owned a jewelry store.'
I had no idea you could make that much in a jewelry store.
When I was a little older and he was deceased I learned the truth.
During the Great Depression he ran a pawn shop. In order to eat, people came to him with their valuables. IE, if they had an antique carved oak table handed down through generations that was worth $500 he would give them $20. They would take it.
He would then contact dealers in larger cities who knew the value was $500 and he sold it to them for $300. He made $280 off the deal.
By the time the Great Depression was over he was rich enough to retire.
The lesson: During very tough economic times, the intelligent do very very well. The stupid do not.
