Here's my assessment of the situation. Not from a parents point of view, but rather from someone who had a similar attitude about the same time in life, and observations of family members and friends going through similar situations with their kids.
It seems to be fairly typical of someone younger than 18. From 2 to 12 they want to follow and be part of everything their parents do. Around 12 to13 they start to get independent thinking they're all grown up and can make their own decisions. They have little or no concept as to how the money comes in to keep them clothed, fed, and puts those spending dollars in their pockets.. They think everyone has money, and all you need to do to get it is ask your parents for it.
About that time in their lives they think it's more important to hang out with their buddies and show off to the girls than be stuck getting their hands dirty with dad. You've asked him to give up his social life, which by the way lasts from the moment he wakes up in the morning to the time he hits the sack in the evening, to work for the same money that's been coming in on a regular basis with no effort on his part.
It was explained to me during those years that "You're going to have to work for a living when you grow up, so you might as well learn to do it at home". It wasn't all that painful once I understood the rules, and it certainly had it's rewards.
Keep in mind that about that time in a child's life both the parents and the child go through huge changes. The child suddenly knows (or think they know) all they need to know, and the parents suddenly become dumb as tree stumps. I thought it was an instant transfer of knowledge. How did my parents get this far in life being as dumb as they were. That phase could last several years or only a few minutes depending on the reaction of the parents.
In my case the phase was somewhat short lived. It only took a few weeks to comprehend I wasn't the source of the cash I was spending, and to keep that source flowing I had to make some changes. Begrudgingly I went along with the program, but knew deep down I was the smartest kid on the planet. It only took a few months before the tables started to turn. For some reason I'd lost a big part of all that knowledge I thought I had, and my parents suddenly emerged from being dumb as stumps. The older I got the dumber I got, and the smarter my parents became. In the end it all worked out.
