I'm saying I'd rather have a dude in a digger than a hundred folks who need to be supplied, some of them drunk, some of them thieves, some of them just plain bad at digging and only making a mess of the dig site.
In this metaphor, your dude in a digger could also be drunk or a thief or bad at his job, and that'd be a bigger problem vs. a few people from a 100 person hand crew.
