I actually agree with most of what you say, but I think that sometimes the attention given to learning disabled kids amounts to more of quantity (teaching to the test) than quality (teaching them life skills suited to their paticular abilities and talents)
Just remember that our current public education system was originally designed to churn out factory workers, and unfortunately a lot of that model remains. I think parents should consider a lot of options for their children. The standard public school may not work for their kid and they may need to take time to explore other possibilities.
