ELI5: How things like segregated high school proms can still exist today?

I feel like once a month you hear of a story like this where kids are having their first desegregated Prom. How is this still going on?

The one you are hearing about isn't an official segregated prom.

The school has no official prom.

A bunch of rich people, who happen to be white, hold their own unofficial prom for white kids in the town.  This doesn't make it not racist (it totally is) but it isn't as if the school (or city, or state, etc) are enforcing the segregation. The white prom is invitation only on private property so they are ~~not technically~~ being racist (which they are) they are turning away uninvited guests (which is legal).

The black community also has a prom that they organize, again privately.
