Side note, like it or not, many people in their early 20's are at least still partially dependent on their parents. Whether this comes in the form of support via a credit card which the person is using to agreed-upon limits (if the kid isn't spoiled and spending it on w/e the fuck he wants) or other forms of support (help with X/Y types of payments) is irrelevant.
Obviously being on your own as early as possible is good (that doesn't happen in a day nor a month but rather in at least the 18 years you were growing up), but scenario above is not out of the ordinary anyway.
