Back to the "rich" thing, Badger's post reminded me of a previous career, and a lady I met one day. I was very new at the time and was given odd jobs while I was still learning aspects of the job necessary to be able to take on my own assignments. One day I was given a cashier's check for just over a million dollars made out to a woman whose name I'd only seen on a spreadsheet. I had to drive out to her house and deliver the check to her. Apparently her bank had refused the deposit, but the oil and gas company was still obligated to pay her, and since direct deposit had failed, delivery was apparently the next option. (Never understood why it wasn't mailed to her address.) I'd previously worked at a bank and the only thing I could think of was a federal law (at least at that time, not sure about now) that required a bank to keep in cash-on-hand at least 10% of it's total demand deposits. Most banks have a cash limit for various reasons, so hypothetically that limits deposits. She used a small, local bank, which obviously carries lower limits than, say, Chase or Wells Fargo or something like that. No idea if that was the problem, but I couldn't think of another reason why her bank didn't take the money.
I drove out to her house, and I don't know what I was expecting, but this was a regular, old, fairly small house in the country, same as my grandparents lived in. The lady was out in the front yard fixing a chicken coop, her husband was nearby also doing chores, both seemed a little miffed about being interrupted, as time was a-wastin' and dammit, they had goats to feed, cows to milk, the whole nine. But they were nice enough. Just country.
That check was for one month's royalty on some wells on their property.
So if Medina et al don't like my other definition of "rich," well, how's that one? If you have so much money that your bank won't take any more of it, you're rich.
