If they were actual multi-crew NPC (not just telepresent SLF pilots) that actually sat in an unused chair and gave an extra pip similar to player multi-crew, they would be worth their pay. Maybe not even just give extra pips but having an NPC that can take the gunnery role and would give the equivalent of grade-A sensors or just better tracking on turrets. Or NPC crew giving longer range or quicker scanning for explorers. Or NPC crew who could auto-dock for you without the need of a docking computer (ok, maybe not that one). There are so many ways NPC crew could actually be useful and *earn* that pay.
Sadly, as per my previous recent thread, NPC crew are not worth it. Active NPC die (or leave or whatever lore Frontier uses) when the mothership is destroyed and not really worth keeping to level up or pay them the crazy fees. Especially that inactive crew just eats up your profits by doing nothing. With Frontier's current implementation, the best tactic is just to hire an expert NPC, use them and fire them before cashing out on bounties, bonds, exploration, trade, etc.
