At one time is was quite normal for a someone in high school to attend school AND work, however, kids these days have so much more to learn than we did which mean longer school hours and more time spent with homework (i.e. less time available for work hours). Granted, a lot of those school courses could be dumped as they are little more than 'feel good' worthless subjects IMO.Never understood why kids couldn't study AND work, rather why it's one or the other for parents. I did both.... I had to. Life is going to be rough if you think that just getting good grades will get you things. Just sayin.
Another factor worth considering is that many employers are no longer willing to give kids a chance at entry level jobs, nor are employment laws as lenient as they use to be AND so many more parents want to shower their offspring with all the things that they didn't have as a youngster - forget about the idea of having to work for anything
