It's only reality because people accept it. If we stop accepting it the reality can be changed. For example, for several hundred years many people accepted slavery and believed owning people was justifiable. When enough people decided not to accept that reality it was changed fairly quickly.
Practices can change, and it's nice to think that once we realized it was possible for "owning people" to not be a thing, we simply made it not a thing, but in fact mindsets can be the slowest to change.
Eradication of an evil social practice is not like invention of a science or technology. We invent the car or the computer, and 25 years later it's in every country on the planet. The Father of History mentions the ills of slavery, and 2500 years later we still haven't quite got this thing licked.
Sorry to be a bit pedantic, but reality exists independent of belief or acceptance. However, a belief in whether or not a person can change that reality at some future point, I think is a more accurate description of the quality you're describing.
While generally you are of course correct, this is not always the case. Some facets of reality have been willed/believed into existence. Nations and social orders are real, but only exist as long as people believe in them. For example, when in 1991 people stopped believing in the existence of the USSR, it was erased from the objective reality in a very brief span of time.
It can be similarly argued that the modern income/opportunity distribution owes its continues existence to the fact that enough people believe that it exists and is lawful.
Do you object to the notion that the USSR, like any country, was in a way an imaginary entity, or to the notion that it mainly ceased to exist because the its citizens decided to imagine something else and actually pulled it off?
> When you go too far up, abstraction-wise, you run out of oxygen. Sometimes smart thinkers just don’t know when to stop, and they create these absurd, all-encompassing, high-level pictures of the universe that are all good and fine, but don’t actually mean anything at all.
Slavery and owning people is still legal, explicitly so in some countries, less explicitly so where sweatshops/slave labor and factory economies function, and implicitly so in places like America and Europe, especially in high churn job sectors where employers figured out you can exploit a constantly new labor pool and by the time they figure it out there is a new batch of suckers to take advantage of(Uber is an example of this model.) Slavery and owning people never went away, it just got better at disguising itself. It will never go away either, because that is how reality functions (or else reality wouldn't function that way)
It's only reality because people accept it. If we stop accepting it the reality can be changed. For example, for several hundred years many people accepted slavery and believed owning people was justifiable. When enough people decided not to accept that reality it was changed fairly quickly.
