As adult with job and kids, I honestly don't work as much as a kid described in that comment. It is in fact way less competitive. I get a good pay, my job is reasonably interesting (ai can make it sux and probably will, but we are not there yet). There are parts that sux or where I am under pressure, but overall, it is better to be an adult then to be teenager trying to get to competitive school.
And for the record, I had to work less to get to good school back then.
