Why not? Except for the easily hide-able tattoo, they look like average white kids on a camping trip. I don't see why people always have to link productivity with what people do on their free time.
I had far wilder times in my teens and early twenties at least every other night. Yes, it was dangerous and risky but the most incredible things in life come with huge risk. Doing everything and exploring helped me figure out who I am and what I want out of life.
During my college years, I studied engineering full time and started my own business to support myself. I've been self-sufficient and haven't asked my parents for a penny since I left home at 17.
The difference might be that you never had your picture taken during any of those wild times, or had it broadcast to the entire world, in full color, almost instantly. It’s not that the activities indulged in render the indulgees unfit, but rather the notoriety that will accompany them because they were unwise enough to engage in their wild times in a very, very public place, during the day time, and in front of the cameras.
The difference is that you didn’t actively disrupt the work routine with others while stinking up a park.
