I’m including only actually competent, full time editors, with sufficiently high reputation that their decisions will be taken seriously. There’s definitely not 50000 of those. A huge number of journals by numerical count, along with their ‘editors’, are literally laughed at in many fields. As you’ve mentioned, trying to expand the actually reputable number by 10x, 20x, etc… is a huge problem. Hence it has to be paid for, quite highly paid for, otherwise the coordination problem is probably impossibly difficult.
