Scavenger World: Leaving aside companies like Probable Technologies, ICC and their professional xenoarchaeology-for-profit efforts, this is subverted; while there are any number of vultures happy to pick over cemetery worlds to loot them of recoverable goods or materials, or indeed of waiting around worlds about to become such worlds (i.e., in the throes of internal war or collapse) to get a good head start on the picking over, most of these are offworlders. Most major disasters either let people pick up in a decade or two, or else kill too many people too fast to let the survivors live into a scavenger-world scenario, at least not for long.
