I skimmed over that article about 'emotional intelligence'. Personally, I think most people (children and adults) could benefit from being taught 'emotional intelligence'. These 5 things the article pointed out are profoundly important for any individual to know.
1)
Self-awareness. Knowing our own emotions.
2)
Self-regulation. Being able to regulate and control how we react to our emotions.
3)
Internal motivation. Having a sense of what’s important in life.
4)
Empathy. Understanding the emotions of others.
5)
Social skills. Being able to build social connections.
Unfortunately it can be very challenging for a public school teacher to teach a subject like 'emotional intelligence' because many people feel that teaching these skills is the parents job. However, for anyone who has taught children or worked in fields with children, you know there are many kids who could benefit from being taught these skills. In addition, anyone who has worked in any field also knows there are a lot of people in general who could benefit from being taught 'emotional intelligence' skills.
So should emotional intelligence be taught in schools. I would say yes but it would have to be woven into the context of other subject lessons and even then you run the risk of wading in some dangerous waters, which a lot of teachers don't want to risk. However, 'emotional intelligence' falls under the scope of school counselors, if school counselors would pick that up and get involved in teaching 'emotional intelligence' skills that would be wonderful.
The way the US school systems work now, in order to teach 'emotional intelligence' there would have to be some kind of standardized methods approved by each state that could be followed by all teachers. This is to prevent people from teaching their own interpretation of 'emotional intelligence'. This may or may not exist at this point, Im not sure.
The department of education in Massachusetts has a pretty good standardized methodology for teaching bullying prevention. Heres a link for anyone interested. They've done a good job putting this together.

There probably are some other states out there weaving 'emotional intelligence' into their curriculum but I would imagine its probably few and far between. At this point I would imagine most of it is aimed more at addressing bullying, which falls under the category of 'emotional intelligence', but the wheels of institutional bureaucracy turn very slowly and even though 'emotional intelligence' may someday find its way into school curriculums it will probably be a slow go.
Interesting subject.
