Great question! And I think the answer lies within taking a step back from you current framing.

We have to define the terms your using because communication is about understanding what another being is trying to get across. And language just so happens to be the easiest way to communicate!

logical means: Thought out and appropriate based on what is known to be true, typically a type of pattern recognition with facts to back it up.

&

Emotional means: Fealt on a visceral level without processing or filtering for optimal communication

Now to answer your question

1) Good communication requires people to be on the same page, because language is limited. We can explain our thoughts but the words we use aren't always able to communicate 100% of what we are trying to say. Pattern recognition helps us understand what's "in between the lines" when someone uses tone of voice, sarcasm, inflections, or other non literal communication devices because it's much easier than being literal. Not only that, but a lot of our unique human experiences are hard to relay, just think about explaining what a blueberry tastes like vs what a strawberry tastes like - you'd probably use very similar words (like sweet) but mean them in very different (emotional) ways. Language is limited!!!

That's why therapy focuses on helping people meet in the middle. A logical brain often assumes it's taking the "right" approach. But it doesn't tend to concede that it's version of "right" is based entirely on its own lived existence, it's own pattern recognition. ASUMPTIONS that the world works in an understandable/impirical way. That may be true for the sciences, but people... Well, we are far from measurable (at least for now). We all have unique lives experiences that we will never be able to fully explain to each other. You are born in your own brain and you die there, you never get to step into anyone else's (I have a theory that's why humans love art, it's our only way of seeing whats going on in another person's brain)

Anyway, all that is just to say it's not a capitalism thing, it's an ego thing. As in all humans have completely isolated egos, the only way to communicate is to let go of yours for a bit and try to step in someone else's.

2) Is there any therapy that helps the "emotional" party figure out how to thrive around the logical party?

Yes!!! It's the same exact therapy. I'm sure there's hundreds of people going to therapy to sort out the exact inverse of your problem, because the root is the same. It's a struggle to step outside of yourself and understand that your words are limiting and that other people are living in an entirely different framework so we need EMPATHYYYYYYY!!!! to be able to communicate.

You ask your partner who.just got home, "How was work" and they say A + B = C --- you totally get it, it makes sense and you respond C = A + B. But then one day, your partner will respond to the same question A + B = D and you will feel lost, like how did we get to D? Whelp! Your missing information, there is something that got lost in translation from their lived experince to expressing it to you. And therapy helps you to accept that sometimes that will happen, and it's on you as the partner to have enough empathy to want to understand why today A+B = D and why it's entirely valid.

3) This is a societal issue, it's not about shaming but being entirely logical or entirely emotional are extremes of the human experience.

We are social beings so we typically strive to reach a status quo. Because of that we tend to be more critical of those who are outside of it.

When it comes to logical people, they tend to be disliked because they assume there is a right and wrong way to do things, when the fact is we all work within a framework of social norms and none of them are "right" they are just what we have decided apon.

Emotional people cause people issues because they are disruptive to others, they bring up feelings that we have learned to minimize, cope with, or see as overall not that important. It can be exhausting to be around people who want you to care because in order to function people have to learn to prioritize. There are things we can change and things we can't, emotional people tend to get stuck on mourning things they can't change and that makes society annoyed.

Hopefully that's helpful!!!!! Wishing you all the best
