Ask HN: Allowance for kids?

For those of you with children, what is your approach to allowance? The three common approaches are having a regular allowance, tying it to chores, or no allowance at all. That said, there can be huge variations once you get into the details. I'd love to hear how you help (or helped!) your kids grow into financially responsible adults.

If you yourself had an allowance structure set up when you were growing up that you think had positive impact, would love to hear about it as well.
