Earth

Around 10 billion people, pretty bad inequality, but not apocalyptic level. Basically current earth but ratcheted up a bit. No united government, UN still exists but is just as impotent as it is currently. Even big governments like US and China are very beholden to corporations that have a multi-planetary presence. R&D departments at space companies are bigger and more innovative than any government space agency.

Earth Orbit
Several research stations and construction projects are in earth orbit. There are hotels, but they are generally on the cheaper side. A middle class family on earth could reasonably stay at an orbital hotel for a week vacation. Most of what happens in earth orbit is

construction.
