Game forgives some inefficiency, so it's "exhaust all researches from the person", the only exception is raider buzzards whom I research once, grav harness on processing is worth more for me-> enslave if possible -> rob if not -> sell if not. I never recruit workers and don't use pimping since they started to waste prison space.
Slaves generate money (honestly - optional for me, would've used them even if they didn't) and save space (I'm a hoarder, it makes me use less buildings)
So far all my gambling needs are covered by mint,
