It's because of the game mechanics.
I firmly believe we'd have more Humans in D&D if race gave no mechanical benefit whatsoever and it was purely a flavor thing a player would append to their character story upon creation.
We see all the time people here talk about not wanting or bothering with "character backgrounds" or "character histories" and instead want their story to come out of gameplay at the table. If a character's race became just one more thing you'd create in your character's "background" or "history" and had no impact at the table... I believe a large number of players would stop bothering to choose.
Some players of course would continue to select a race for their character-- those that actually created a background and past history of their PC prior to adventuring-- but that number would be less than it is now because of all the players who select non-human races because of the mechanical benefit.
Yes, I'm jaded.![]()
I think there are lots of players who enjoy nonhuman races/heritages for nonmechanical reasons.
But I can happily admit that as a somewhat competitive-minded player, who likes options and powers, that the first time I regularly played humans in D&D is when 3rd edition actually gave them benefits beyond class selection, and let them multiclass like everyone else.
Similar to how the first time I played a single-classed Fighter for any length of time was in 4th ed, once Fighters got cool options and abilities.
