Maybe it's because of better diagnostic capabilities, but there seems to be a lot more "special education" issues than there were in the past.
- We can diagnose learning disabilities more accurately, where a learning disability is anything that impedes learning when using "normal" teaching techniques
- We have programs and techniques that enable these children to learn despite their difficulties
- Using these programs educators have shown that these children can keep up with and even learn above their grade level, whereas previously they may have simply been labeled misfits or retarded and allowed to regress
We've taken advantage of the laws and these programs for our own children, two of which have been diagnosed as falling on the autism spectrum (aspergers), and one of which had a speech impediment.
With normal teaching techniques they would be characterized as unruly, lazy, and bothersome to other students. If you know that they interpret the world differently than other kids, and you apply slightly different teaching techniques they turn into model students.
So yes, it's a bother for everyone - to some degree it would be nice if kids were all similar enough that one wouldn't need to take special measures, but given that this is the situation, everyone is better off knowing the issues and having the tools to deal with the outliers.
Entertainer? How's that depressing?!
Turns out that, psychologically, entertaining is extraordinarily draining (your entire existence depends on whether other people like you or not), and that's on top of the likelihood of becoming addicted to the emotional rush of applause/etc. The times inbetween the limelight can be very depressing, compared to the highs one gets on stage.
