Were I them, I would be focusing my efforts this generation and next in repopulating, reinforcing cultural teachings and unity and acquiring wealth. The Jews are phenomenal example of recovering from their holocaust. I have witnessed small Jewish communities explode in population and influence over a span of only thirty years.

The overkill theory has been pretty much shot down. For one thing, megafauna disappeared worldwide at roughly the same time, there have not been mass remains found near native settlements, and those that disappeared were primarily predators, not food herbivore species. Competition with humans was likely a cause, maybe even the leading cause but it wasn't overhunting.
Star Trek seems a bit more egalitarian. There's hierarchies where there needs to be, and the Captain certainly get his own private toilet, but in things like restaurant reservations except where the owner specifically lets someone skip ahead or come in with no reservation based on merit I think it is equal.

Some of them may be able to be bought out individually or through a hostile takeover, others like Sony, who are part of a major conglamerate, you have to convince to actually sell.
