I do agree with some of the points in the article. In particular, I do believe that children should sometimes be allowed to be bored. In my view, it's boredom that often feeds the imagination, fosters creativity and develops self-sufficiency and motivation.
I also think that too much use of mobile phones and computers has a detrimental effect on the ability to focus on one thing for any length of time, and on developing face-to-face social skills.
Having said that, I also think our education system is too prescriptive and shuts down motivation and creativity. (I do not blame the teachers for that - their hands are tied).
I think it was a good idea for mainstream schools to include children with special needs, since they are part of society and should not be segregated within it - and children should learn to welcome and adapt to differences in their peers. However, it is has been done on the cheap - with teachers given nowhere near enough extra support.
I think, despite admirable intentions, the lack of necessary resources has disadvantaged special needs students. In my later working life I retrained as an adult literacy teacher and on occasions took a class of adults with learning difficulties. I found that all of the (mature) students, (who were of the age when special schools were the norm), were surprisingly competent in reading, writing, spelling and comprehension.
Several years ago, when I went with my daughter to look at the choices of secondary schools for her son, I was dismayed when a history teacher told me he did not really expect a special needs student to participate in the lesson, but the boy was useful for distributing handouts.
I think where the article falls down is in its sweeping generalisations. I really don't think all kids "get everything they want, when they want it". Some children get very little of what they want, particularly if their caregivers are struggling with financial,housing or health issues - or their parents are emotionally distant.
Finally, I agree with the writer regarding parents' "emotional availability". I think it is probably the most important component of parenting, and one which I, unwittingly, fell down on.
