enslaved India.
If, that is, the computer Minds which will rule corporations
and therefore the world, choose to include any version of
human beings in their interstellar expansion, at all.
Not to mention the civil rights of aliens with a more
primitive culture. (If the aliens have a less primitive
culture, then they - or their computers and corporations -
will be rulers. Unless a plucky fighter pilot can fly a
nerd with a laptop inside the mothership without getting
assimilated first...)
If corporations control space travel then they also will

In Andre Norton's _Sargasso of Space_ and sequels, newly
discovered planet are auctioned between companies -
although Norton apparently has an un-commercial
space police force called The Patrol, too.
Doctor Who has had encounters with commercial imperial
exploitation by humans of other planets; in these cases
he does not necessarily take the humans' side.
Star Trek novel <

which I keep going on about, features a Ferengi businessman
who uses his starship weapons and other superior technology
to conquer and enslave the planet in question, although
