Your definition is off in a few ways:

Middlemen are brokers, intermediaries. Almost every job is in the middle of something including the ones labeled “real” - e.g. manufacturing uses some things to produce others. Some of the jobs you refer to as middle, are not actually middle - e.g. accounting.

You probably wanted to refer to white collar jobs or maybe just services.

Middleman are not what you think and your argument sounds off from the bat just because you use that word.
