Space colonization would be the equivalent of living at Dubai, and arguably owning the place, because living there would be incredibly more expensive than stacking people in a camp on Earth.
The only imaginable logic where you offload "excess humans" in space, imply a world government defending "excess humans" right to a quality of life equivalent than Earthnoid, conceding that if Earth isn't enough for billions to have 100m2 house, then they have to replicate Earth in space.

If we go for separate governments instead, you'd likely be unspeakably rich because colonies would be paid from extracting space-mineral like platinum or fusion fuel extraction, even without owning the place only well-educated people would be allowed to live in such a world ruled by science.

The infrastructure needed to even build such colonies mean you'd be able to travel everywhere in the solar system as you want, we will assume only the truly rich people would have their personal spaceship.

>immigrating to America in the 1800's
... funny example since their descendant definitely got the best deal, and arguably so did the original settler/immigrant since America was the place to be.
Unclaimed lands, untouched resources, plenty of rooms...
As a country at least, obviously current US has the worst class disparity and 0.01% of plutocrat control 99.99 of (wage-)slaves.
