From the New York Times, “Why You Should Tell Your Children How Much You Make”:
When Scott Parker wanted his six offspring to know more about the value of money, he decided to do something that many parents would consider radical: show them exactly what he earned.
One day, he stopped by his local Wells Fargo branch in Encinitas, Calif., and asked to withdraw his entire monthly salary in cash. In singles. It took 24 hours for the tellers to round up that many bills, so he returned the next day and took away the $100 stacks in a canvas bag.
His oldest son, Daniel, who was 15 at the time, remembers the moment his father walked into the house and dumped the $10,000 or so on a table. “It looked like he had robbed a bank,” he said.
Parker was trying to teach his kids a lesson about the value of money. But the lesson I would learn from this is “If somebody, like a bank teller, works in a service job, and makes a lot less money than I do, I can make them spend a full day of their life carrying out an incredibly tedious task without thinking about whether this is a reasonable way for them to spend their time.”
Quomodocumque 
I was under the impression it took 24 hours because the bank simply didn’t have that many one dollar bills on hand. They probably had to order all those bills with the next armored car delivery, and the bills were probably delivered in $100 bundles.
Anyway the bank tellers would have been paid the same and worked the same hours whether or not Parker had come in. Does it really make a difference to them?
I read the entire article and thought, “who now takes home $10,000/month, let alone 20 years ago, when he did this project”? I’m all for transparency, but as often is an issue with the NYT, they tend to feature either the very wealthy or the struggling.
