I don't wonder that, but I have always wondered if it is a communist theory. It was developed in communist Russia in the 1970s, by someone who worked for a type of 'planning agency', and the types are force-fit into these perfect relationships, jobs, etc. My theory is that it was going to be used to 'select' people for families, arranged marriages, and maybe jobs the way people were forced into careers in the USSR. I had therefore always wondered if - for real - it was developed for communist purposes. Even if it was, it still makes me LMAO however....
