It depends. It's possible to find a younger programmer who is less confident in their skills or vastly underestimates his net worth. This tends to normalize with age and experience, so an older programmer with the same skillset is likely going to be more expensive simply because they know how much they can ask for. Similar to the effect of women being paid less because they are less likely to ask for raises.
