Sonic in the Archie Comics and SatAM cartoon was the child of nobles, with his uncle being court scientist. He even became king in the Archieverse. Sonic in Underground was a literal prince.
These depictions have since been retconned of course. Still -- I wonder if there's something to be interpreted about like, cultural perceptions and human biases
When you consider Sonic, an avatar of teenage rebellion, was almost always written as a child of privilege when the western writers had free rein. Whereas Japanese Sonic (who became the canonical one) has been, from the word 'go', always a homeless drifter whose roots are unknown because they don't matter.
I'd even argue Movie Sonic fits the bill for 'child of privilege'.
He might not be royal/noble, but there were lots of people with eyes on his (innate) superpowers, which lead to him being cared for and trained in secret by Longclaw
